摘要：此外，利用CO2sub>羽流进行地热储能可通过将CO2sub>储存于地质体中来缓解温室效应。本文提出了一个协同地热能储能和二氧化碳封存利用的一体化框架：CO2sub>首先被注入到地热层以进行能量积累。然后，将产生的高能CO2sub>引入到目标油藏中，用于CO2sub>利用和地热能储存。最后，将CO2sub>有效地封存在地质油藏体中。结果表明，随着高能CO2sub>的注入，整个目标油藏的平均温度大幅度提高。在地热能的协助下，CO2sub>的地质利用率更高，从而使驱油效率提高了10.1%。根据对模拟CO2sub>场地的封存潜力的评估，CO2sub>注入110年后，地质体的利用率将高达91.2%，场地内CO2sub>的最终注入量将高达9.529

Rh2sub>O3sub>/hexagonal CePO4sub> nanocatalysts for N2sub>O decomposition

Huan Liu, Zhen Ma

《化学科学与工程前沿（英文）》 2017年第11卷第4期页码 586-593 doi: 10.1007/s11705-017-1659-6

摘要： Hexagonal CePO nanorods were prepared by a precipitation method and hexagonal CePO nanowires were prepared by hydrothermal synthesis at 150 °C. Rh(NO ) was then used as a precursor for the impregnation of Rh O onto these CePO materials. The Rh O supported on the CePO nanowires was much more active for the catalytic decomposition of N O than the Rh O supported on CePO nanorods. The stability of both catalysts as a function of time on stream was studied and the influence of the co-feed (CO , O , H O or O /H O) on the N O decomposition was also investigated. The samples were characterized by N adsorption-desorption, inductively coupled plasma optical emission spectroscopy, X-ray diffraction, transmission electron microscopy, X-ray photoelectron microscopy, hydrogen temperature-programmed reduction, oxygen temperature-programmed desorption, and CO temperature-programmed desorption in order to correlate the physicochemical and catalytic properties.

摘要：

自1998年以来，人们广泛认为Au/Ti基催化剂的Au-O-Ti⁴⁺位点是在相对高温条件下丙烯气相环氧化反应的活性位点，但该类催化剂的H2sub>有效利用率普遍较低值得注意的是，该活性位点主导反应时，最佳温度可从200 °C显著降低至138 °C，并使催化剂保持前所未有的43.6%的H2sub>有效利用率、90.7%的环氧丙烷（PO）并且利用原位紫外-可见光谱（operando UV-vis）技术研究了Ti-OOH反应中间体的动态演化过程，结果表明，在Au-O-Ti³⁺活性位点上的Ti-OOH的生成速率比在Au-O-TiTi³⁺位点促进了Au和Ti³⁺之间的电子转移，从而增强了催化剂对O2sub>的吸附能力，有效促进H2sub>O2sub本工作所报道的结果为强化丙烯直接气相环氧化反应的H2sub>有效利用率提供了新的思路，而且为低温下丙烯直接气相环氧化反应的工业化推进开辟了新的机会。

CO2sub> methanation and co-methanation of CO and CO2sub> over Mn-promoted Ni/Al2sub>O3sub> catalysts

《化学科学与工程前沿（英文）》 2016年第10卷第2期页码 273-280 doi: 10.1007/s11705-016-1563-5

摘要： A series of Mn-promoted 15 wt-% Ni/Al O catalysts were prepared by an incipient wetness impregnation method. The effect of the Mn content on the activity of the Ni/Al O catalysts for CO methanation and the co-methanation of CO and CO in a fixed-bed reactor was investigated. The catalysts were characterized by N physisorption, hydrogen temperature-programmed reduction and desorption, carbon dioxide temperature-programmed desorption, X-ray diffraction and high-resolution transmission electron microscopy. The presence of Mn increased the number of CO adsorption sites and inhibited Ni particle agglomeration due to improved Ni dispersion and weakened interactions between the nickel species and the support. The Mn-promoted 15 wt-% Ni/Al O catalysts had improved CO methanation activity especially at low temperatures (250 to 400 °C). The Mn content was varied from 0.86% to 2.54% and the best CO conversion was achieved with the 1.71Mn-Ni/Al O catalyst. The co-methanation tests on the 1.71Mn-Ni/Al O catalyst indicated that adding Mn markedly enhanced the CO methanation activity especially at low temperatures but it had little influence on the CO methanation performance. CO methanation was more sensitive to the reaction temperature and the space velocity than the CO methanation in the co-methanation process.

Al2sub>O3sub> and CeO2sub>-promoted MgO sorbents for CO2sub> capture at moderate

Huimei Yu, Xiaoxing Wang, Zhu Shu, Mamoru Fujii, Chunshan Song

《化学科学与工程前沿（英文）》 2018年第12卷第1期页码 83-93 doi: 10.1007/s11705-017-1691-6

摘要： A series of Al O and CeO modified MgO sorbents was prepared and studied for CO sorption at moderate temperatures. The CO sorption capacity of MgO was enhanced with the addition of either Al O or CeO . Over Al O -MgO sorbents, the best capacity of 24.6 mg-CO /g-sorbent was attained at 100 °C, which was 61% higher than that of MgO (15.3 mg-CO /g-sorbent). The highest capacity of 35.3 mg-CO /g-sorbent was obtained over the CeO -MgO sorbents at the optimal temperature of 200 °C. Combining with the characterization results, we conclude that the promotion effect on CO sorption with the addition of Al O and CeO can be attributed to the increased surface area with reduced MgO crystallite size. Moreover, the addition of CeO increased the basicity of MgO phase, resulting in more increase in the CO capacity than Al O promoter. Both the Al O -MgO and CeO -MgO sorbents exhibited better cyclic stability than MgO over the course of fifteen CO sorption-desorption cycles. Compared to Al O , CeO is more effective for promoting the CO capacity of MgO. To enhance the CO capacity of MgO sorbent, increasing the basicity is more effective than the increase in the surface area.

The stabilization effect of Al2sub>O3sub> on unconventional Pb/SiO2sub> catalyst

《化学科学与工程前沿（英文）》 2023年第17卷第10期页码 1423-1429 doi: 10.1007/s11705-023-2315-y

摘要： Similar to Sn, Pb located at the same group (IVA) in the periodic table of elements, can also catalyze propane dehydrogenation to propene, while a fast deactivation can be observed. To enhance the stability, the traditional carrier Al₂O₃ with a small amount, was introduced into Pb/SiO₂ catalyst in this study. It has been proved that Al₂O₃ can inhibit the reduction of PbO, and weaken the agglomeration and loss of Pb species due to its enhanced interaction with Pb species. As a result, 3Al15Pb/SiO₂ catalyst exhibits a much higher stability up to more than 150 h. In addition, a simple schematic diagram of the change of surface species on the catalyst surface after Al₂O₃ addition was also proposed.

Cu-doped Bi/Bi2sub>WO6sub> catalysts for efficient N2sub> fixation by photocatalysis

《化学科学与工程前沿（英文）》 2023年第17卷第10期页码 1412-1422 doi: 10.1007/s11705-023-2312-1

摘要： In this paper, Cu-doped Bi₂WO₆ was synthesized via a solvothermal method and applied it in photocatalytic N₂ immobilization. Characterization results showed the presence of a small amount of metallic Bi in the photocatalyst, indicating that the synthesized photocatalyst is actually Bi/Cu-Bi₂WO₆ composite. The doped Cu had a valence state of +2 and most likely substituted the position of Bi³⁺. The introduced Cu did not affect the metallic Bi content, but mainly influenced the energy band structure of Bi₂WO₆. The band gap was slightly narrowed, the conduction band was elevated, and the work function was reduced. The reduced work function improved the transfer and separation of charge carriers, which mainly caused the increased photoactivity. The optimized NH₃ generation rates of Bi/Cu-Bi₂WO₆ reached 624 and 243 μmol·L^–1·g^–1·h^–1 under simulated solar and visible light, and these values were approximately 2.8 and 5.9 times higher those of Bi/Bi₂WO₆, respectively. This research provides a method for improving the photocatalytic N₂ fixation and may provide more information on the design and preparation of heteroatom-doped semiconductor photocatalysts for N₂-to-NH₃ conversion.

ZnFe2sub>O4sub> deposited on BiOCl with exposed (001) and (010) facets for photocatalyticreduction of CO2sub> in cyclohexanol

Guixian Song, Xionggang Wu, Feng Xin, Xiaohong Yin

《化学科学与工程前沿（英文）》 2017年第11卷第2期页码 197-204 doi: 10.1007/s11705-016-1606-y

摘要： ZnFe O -BiOCl composites were prepared by both hydrothermal and direct precipitation processes and the structures and properties of the samples were characterized by various instrumental techniques. The samples were then used as catalysts for the photocatalytic reduction of CO in cyclohexanol under ultraviolet irradiation to give cyclohexanone (CH) and cyclohexyl formate (CF). The photocatalytic CO reduction activities over the hydrothermally prepared ZnFe O -BiOCl composites were higher than those over the directly-precipitated composites. This is because compared to the direct-precipitation sample, the ZnFe O nanoparticles in the hydrothermal sample were smaller and more uniformly distributed on the surface of BiOCl and so more heterojunctions were formed. Higher CF and CH yields were obtained for the pure BiOCl and BiOCl composite samples with more exposed (001) facets than for the samples with more exposed (010) facets. This is due to the higher density of oxygen atoms in the exposed (001) facets, which creates more oxygen vacancies, and thereby improves the separation efficiency of the electron-hole pairs. More importantly, irradiation of the (001) facets with ultraviolet light produces photo-generated electrons which is helpful for the reduction of CO to ·CO . The mechanism for the photocatalytic reduction of CO in cyclohexanol over ZnFe O -BiOCl composites with exposed (001) facets involves electron transfer and carbon radical formation.

《化学科学与工程前沿（英文）》 2021年第15卷第4期页码 882-891 doi: 10.1007/s11705-020-1990-1

摘要： Hydrogen fuel has been embraced as a potential long-term solution to the growing demand for clean energy. A membrane-assisted separation is promising in producing high-purity H . Molecular sieving membranes (MSMs) are endowed with high gas selectivity and permeability because their well-defined micropores can facilitate molecular exclusion, diffusion, and adsorption. In this work, MXene nanosheets intercalated with Ni were assembled to form an MSM supported on Al O hollow fiber via a vacuum-assisted filtration and drying process. The prepared membranes showed excellent H /CO mixture separation performance at room temperature. Separation factor reached 615 with a hydrogen permeance of 8.35 × 10 mol·m ·s ·Pa . Compared with the original Ti C T /Al O hollow fiber membranes, the permeation of hydrogen through the Ni -Ti C T /Al O membrane was considerably increased, stemming from the strong interaction between the negatively charged MXene nanosheets and Ni . The interlayer spacing of MSMs was tuned by Ni . During 200-hour testing, the resultant membrane maintained an excellent gas separation without any substantial performance decline. Our results indicate that the Ni tailored Ti C T /Al O hollow fiber membranes can inspire promising industrial applications.
