Jie Mao, Xie Quan, Jing Wang, Cong Gao, Shuo Chen, Hongtao Yu, Yaobin Zhang

《环境科学与工程前沿（英文）》 2018年 第12卷 第6期 doi: 10.1007/s11783-018-1060-9

摘要：

OH played a key role in heterogeneous Fenton-like catalytic oxidation of organic pollutants.

Doping Cu into BiFeO3 promoted the generation of Fe2+ and then facilitated the effective formation of •OH.

Cu-doped BiFeO3 exhibited higher catalytic performance for phenol degradation than non-doped BiFeO3.

Degradation of antipyrine in the Fenton-like process with a La-doped heterogeneous catalyst

Shicheng Wei, Cuiping Zeng, Yaobin Lu, Guangli Liu, Haiping Luo, Renduo Zhang

《环境科学与工程前沿（英文）》 2019年 第13卷 第5期 doi: 10.1007/s11783-019-1149-9

摘要： Abstract A La-doped Co-Cu-Fe catalyst was synthesized for the antipyrine (ANT) removal. The La-doped catalyst had higher ANT removal than the control (95% vs. 54%). La reduced the particle size and increased the specific surface area of catalyst. The aim of this study was to synthesize a novel lanthanum (La) doped catalyst and to investigate antipyrine removal in wastewater using the Fenton-like process with the catalyst. The La-doped Co-Cu-Fe catalyst was synthesized using the modified hydrothermal method. Results showed that the La-doped catalyst had higher specific surface area and lower particle size than the catalyst without La doping (i.e., the control) (267 vs. 163 m2/g and 14 vs. 32 nm, respectively). Under the conditions of catalyst dosage 0.5 g/L, H2O2 concentration 1.70 g/L, and NaHCO3 0.1 g/L, the antipyrine removal within 60 min using the Fenton-like process with the La-doped catalyst was much higher than that with the control (95% vs. 54%). The hydroxyl radical concentration with the La-doped catalyst within 60 min was two times higher than that with the control (49.2 vs. 22.1 mg/L). The high catalytic activity of La-doped catalyst was mainly attributed to its high specific surface area based on the X-ray photoelectron spectroscopy result. Our La-doped catalyst should have great potential to remove antipyrine in wastewater using the heterogeneous Fenton-like process.

Fe-Mn-sepiolite as an effective heterogeneous Fenton-like catalyst for the decolorization of reactive

Chengyuan SU,Weiguang LI,Xingzhe LIU,Xiaofei HUANG,Xiaodan YU

《环境科学与工程前沿（英文）》 2016年 第10卷 第1期   页码 37-45 doi: 10.1007/s11783-014-0729-y

摘要： A study of the decolorization of reactive brilliant blue in an aqueous solution using Fe-Mn-sepiolite as a heterogeneous Fenton-like catalyst has been performed. The Fourier transform infrared (FTIR) spectra of the catalyst showed bending vibrations of the Fe-O. The X-ray diffraction (XRD) patterns of the catalyst showed characteristic diffraction peaks of α-Fe O , γ-Fe O and MnO. A four factor central composite design (CCD) coupled with response surface methodology (RSM) was applied to evaluate and optimize the important variables (catalyst addition, hydrogen peroxide dosage, initial pH value and initial dye concentration). When the reaction conditions were catalyst dosage= 0.4 g, [H O ]= 0.3 mL, pH= 2.5, [reactive brilliant blue] = 50 mg·L , and volume of solution= 500 mL at room temperature, the decolorization efficiency of reactive brilliant blue was 91.98% within 60 min. Moreover, the Fe-Mn-sepiolite catalyst had good stability for the degradation of reactive brilliant blue even after six cycles. Leaching of iron ions (<0.4 mg·L ) was observed. The decoloring process was reactive brilliant blue specific via a redox reaction. The benzene ring and naphthalene ring were first oxidized to open ring; these were then oxidized to the alcohol and carboxylic acid. The reactive brilliant blue was decomposed mainly by the attack of ·OH radicals including surface-bound ·OH radicals generated on the catalyst surface.

Precursor-driven structural tailoring of iron oxychloride for enhanced heterogeneous Fenton activity

《化学科学与工程前沿（英文）》 2023年 第17卷 第10期   页码 1533-1543 doi: 10.1007/s11705-023-2330-z

摘要： Iron oxychloride (FeOCl) is a unique layered material with tunable electronic properties. The conventional synthetic route of chemical vapor transition involves a thermodynamics-driven gas–solid interfacial reaction which often generates macroscopic crystals with stable facets. In this study, through analyzing the effects of the synthetic parameters on the FeOCl synthesis, we discovered the dominant contribution of the α-Fe2O3 precursors on the chemical property of the FeOCl product, and subsequently developed a highly-controllable synthetic route of tailoring the FeOCl structures into small sizes and exposed high-energy facets via a facile and scalable mechanical-chemical approach. The synthesized products could be systematically tuned by the ball-milling conditions of the α-Fe2O3 precursors. With increased milling time, the FeOCl crystallites demonstrated reduced sizes and more exposed (110) facets. Intriguingly, these small-sized FeOCl catalysts exhibited much faster Fenton-like kinetics than the pristine macroscopic FeOCl materials. Specifically, FeOCl catalysts with a 12-hour milling time showed nearly 39 times higher efficiency toward phenol degradation than the pristine FeOCl. The structure-reactivity relationship was further elucidated using the combinatory analysis via density functional theory calculation, electron paramagnetic resonance and radical quenching probe experiments. This work provides a rationale for tailoring the surface structures of FeOCl crystallites for potential applications in environmental catalysis.

Computational design of heterogeneous catalysts and gas separation materials for advanced chemical processing

Huaiwei Shi, Teng Zhou

《化学科学与工程前沿（英文）》 2021年 第15卷 第1期   页码 49-59 doi: 10.1007/s11705-020-1959-0

摘要： Functional materials are widely used in chemical industry in order to reduce the process cost while simultaneously increase the product quality. Considering their significant effects, systematic methods for the optimal selection and design of materials are essential. The conventional synthesis-and-test method for materials development is inefficient and costly. Additionally, the performance of the resulting materials is usually limited by the designer’s expertise. During the past few decades, computational methods have been significantly developed and they now become a very important tool for the optimal design of functional materials for various chemical processes. This article selectively focuses on two important process functional materials, namely heterogeneous catalyst and gas separation agent. Theoretical methods and representative works for computational screening and design of these materials are reviewed.

A mini review on strategies for heterogenization of rhodium-based hydroformylation catalysts

Cunyao Li, Wenlong Wang, Li Yan, Yunjie Ding

《化学科学与工程前沿（英文）》 2018年 第12卷 第1期   页码 113-123 doi: 10.1007/s11705-017-1672-9

摘要： Hydroformylation has been widely used in industry to manufacture high value-added aldehydes and alcohols, and is considered as the largest homogenously catalyzed process in industry. However, this process often suffers from complicated operation and the difficulty in catalyst recycling. It is highly desirable to develop a heterogeneous catalyst that enables the catalyst recovery without sacrificing the activity and selectivity. There are two strategies to afford such a catalyst for the hydrofromylation: immobilized catalysts on solid support and porous organic ligand (POL)-supported catalysts. In the latter, high concentration of phosphine ligands in the catalyst framework is favorable for the high dispersion of rhodium species and the formation of Rh-P multiple bonds, which endow the catalysts with high activity and stability respectively. Besides, the high linear regioselectivity could be achieved through the copolymerization of vinyl functionalized bidentate ligand (vinyl biphephos) and monodentate ligand (3vPPh ) into the catalyst framework. The newly-emerging POL-supported catalysts have great perspectives in the industrial hydroformylation.

Fabrication of MIL-100(Fe)@SiO

《化学科学与工程前沿（英文）》 2016年 第10卷 第4期   页码 534-541 doi: 10.1007/s11705-016-1596-9

摘要： Heterogeneous catalysts with convenient recyclability and reusability are vitally important to reduce the cost of catalysts as well as to avoid complex separation and recovery operations. In this regard, magnetic MIL-100(Fe)@SiO @Fe O microspheres with a novel core-shell structure were fabricated by the self-assembly of a metal-organic MIL-100(Fe) framework around pre-synthesized magnetic SiO @Fe O particles under relatively mild and environmentally benign conditions. The catalytic activity of the MIL-100(Fe)@SiO @Fe O catalyst was tested for the liquid-phase acetalization of benzaldehyde and glycol. The MIL-100(Fe)@SiO @Fe O catalyst has a significant amount of accessible Lewis acid sites and therefore exhibited good acetalization catalytic activity. Moreover, due to its superparamagnetism properties, the heterogeneous MIL-100(Fe)@SiO @Fe O catalyst can be easily isolated from the reaction system within a few seconds by simply using an external magnet. The catalyst could then be reused at least eight times without significant loss in catalytic efficiency.

Linbi Zhou, Hongbin Cao, Claude Descorme, Yongbing Xie

《环境科学与工程前沿（英文）》 2018年 第12卷 第1期 doi: 10.1007/s11783-017-0970-2

摘要： Wet air oxidation (WAO) and catalytic wet air oxidation (CWAO) are efficient processes to degrade organic pollutants in water. In this paper, we especially reviewed the WAO and CWAO processes for phenolic compounds degradation. It provides a comprehensive introduction to the CWAO processes that could be beneficial to the scientists entering this field of research. The influence of different reaction parameters, such as temperature, oxygen pressure, pH, stirring speed are analyzed in detail; Homogenous catalysts and heterogeneous catalysts including carbon materials, transitional metal oxides and noble metals are extensively discussed, among which Cu based catalysts and Ru catalysts were shown to be the most active. Three different kinds of the reactor implemented for the CWAO (autoclave, packed bed and membrane reactors) are illustrated and compared. To enhance the degradation efficiency and reduce the cost of the CWAO process, biological degradation can be combined to develop an integrated technology.

Lignin-based electrospun nanofiber membrane decorated with photo-Fenton Ag@MIF-100(Fe) heterojunctions

《化学科学与工程前沿（英文）》 2023年 第17卷 第7期   页码 930-941 doi: 10.1007/s11705-023-2309-9

摘要： Membrane technology for wastewater remediation has aroused wide interest owing to its unique properties and potential applications. However, it remains challenging to explore green, efficient and robust membrane material and technique for complex wastewater treatment. Herein, we proposed using a simple electrospinning and in situ seeding method to fabricate a lignin-based electrospun nanofiber membrane (LENM) decorated with photo-Fenton Ag@MIL-100(Fe) heterojunctions for efficient separation of oil/water emulsions and degradation of organic dye. Thanks to the embedded lignin in LENM, an ultrahigh MIL-100(Fe) loading (53 wt %) with good wettability and high porosity was obtained. As a result, the hybrid Ag@MIL-100(Fe)/LENM exhibited excellent oil/water emulsions separation efficiency (more than 97%) without a compromise of water flux. Moreover, the hybrid membrane showed an excellent dye removal with degradation of 99% methylene blue within 30 min under illumination, which is attributed to a synergy of dye adsorption/enrichment and photo-Fenton catalytic degradation from Ag@MIL-100(Fe). Therefore, the lignin-based photo-Fenton hybrid membrane can lay the foundation for the preparation and application of green, sustainable and versatile membrane materials and technologies for efficient complex wastewater remediation.

Hydroxyl radical-involved cancer therapy via Fenton reactions

《化学科学与工程前沿（英文）》 2022年 第16卷 第3期   页码 345-363 doi: 10.1007/s11705-021-2077-3

摘要： The tumor microenvironment features over-expressed hydrogen peroxide (H2O2). Thus, versatile therapeutic strategies based on H2O2 as a reaction substrate to generate hydroxyl radical (•OH) have been used as a prospective therapeutic method to boost anticancer efficiency. However, the limited Fenton catalysts and insufficient endogenous H2O2 content in tumor sites greatly hinder •OH production, failing to achieve the desired therapeutic effect. Therefore, supplying Fenton catalysts and elevating H2O2 levels into cancer cells are effective strategies to improve •OH generation. These therapeutic strategies are systematically discussed in this review. Furthermore, the challenges and future developments of hydroxyl radical-involved cancer therapy are discussed to improve therapeutic efficacy.

《环境科学与工程前沿（英文）》 2020年 第14卷 第1期 doi: 10.1007/s11783-019-1191-7

摘要： MEDCC combined with Fenton process was developed to treat real pesticide wastewater. Pesticide removal was attributable to desalination in the MEDCC. High COD removal was attributable to organic distributions in different chambers. The combination of the microbial electrolysis desalination and chemical-production cell (MEDCC) and Fenton process for the pesticide wastewater treatment was investigate in this study. Real wastewater with several toxic pesticides, 1633 mg/L COD, and 200 in chromaticity was used for the investigation. Results showed that desalination in the desalination chamber of MEDCC reached 78%. Organics with low molecular weights in the desalination chamber could be removed from the desalination chamber, resulting in 28% and 23% of the total COD in the acid-production and cathode chambers, respectively. The desalination in the desalination chamber and organic transfer contributed to removal of pesticides (e.g., triadimefon), which could not be removed with other methods, and of the organics with low molecular weights. The COD in the effluent of the MEDCC combined the Fenton process was much lower than that in the perixo-coagulaiton process (<150 vs. 555 mg/L). The combined method consumed much less energy and acid for the pH adjustment than that the Fenton.
