Denitrification performance and sulfur resistance mechanism of Sm–Mn catalyst for low temperature NH-SCR

《化学科学与工程前沿（英文）》 2023年第17卷第5期页码 617-633 doi: 10.1007/s11705-022-2258-8

摘要： MnO_x and Sm–Mn catalysts were prepared with the coprecipitation method, and they showed excellent activities and sulfur resistances for the selective catalytic reduction of NO_x by NH₃ between 50 and 300 °C in the presence of excess oxygen. 0.10Sm–Mn catalyst indicated better catalytic activity and sulfur resistance. Additionally, the Sm doping led to multi-aspect impacts on the phases, morphology structures, gas adsorption, reactions process, and specific surface areas. Therefore, it significantly enhances the NO conversion, N₂ selectivity, and sulfur resistance. Based on various experimental characterization results, the reaction mechanism of catalysts and the effect of SO₂ on the reaction process about the catalysts were extensively explored. For 0.10Sm–Mn catalyst, manganese sulfate and sulfur ammonium cannot be generated broadly under the influence of SO₂ and the amount of surface adsorbed oxygen. The Bronsted acid sites strengthen significantly due to the addition of SO₂, enhancing the sulfur resistance of the 0.10Sm–Mn catalyst.

摘要：

具有单轴面内各向异性的非晶Sm-Co薄膜在信息存储和自旋电子学领域中都具有广阔的应用前景。产生单轴面内各向异性的最有效方法是在薄膜沉积过程中施加面内磁场。然而，这种方法通常需要复杂的设备。本文中，我们报道了一种产生单轴面内各向异性的新方法，只需要将非晶Sm-Co薄膜生长在(011)取向的单晶衬底上，薄膜生长过程中不需要施加任何外部磁场。生长在LaAlO₃ (011)衬底上的非晶Sm-Co薄膜的各向异性常数k_A高达3.3×10⁴ J·详细分析表明，衬底各向异性应变引起的铁磁畴的择优生长，以及薄膜中Sm-Co、Co-Co取向对的有序化，在非晶Sm-Co薄膜单轴面内各向异性的产生上起到了重要作用。这项工作为在非晶Sm-Co薄膜中获得单轴面内各向异性提供了一种新方法。

《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.

CO₂ methanation and co-methanation of CO and CO₂ over Mn-promoted Ni/Al₂

Kechao Zhao,Zhenhua Li,Li Bian

《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.

《环境科学与工程前沿（英文）》 2015年第9卷第3期页码 385-393 doi: 10.1007/s11783-014-0648-y

摘要： The adsorption potential of FMBO, FeOOH, MnO for the removal of Cd , Cu and Pb in aqueous systems was investigated in this study. Comparing to FMBO and FeOOH, MnO offered a much higher removal capacity towards the three metal ions. The maximal adsorption capacity of MnO for Cd , Cu and Pb were 1.23, 2.25 and 2.60 mmol·g , respectively. And that for FMBO were 0.37, 1.13, and 1.18 mmol·g and for FeOOH were 0.11, 0.86 and 0.48 mmol·g , respectively. The adsorption behaviors of the three metal ions on the three adsorbents were all significantly affected by pH values and heavy metal removal efficiency increased with pH increased. The Langmuir and Freundlich adsorption models were used to describe the adsorption equilibrium of the three metal ions onto the three adsorbents. Results showed that the adsorption equilibrium data fitted well to Langmuir isotherm and this indicated that adsorption of metal ions occurred on the three metal oxides adsorbents limited to the formation of a monolayer. More negative charged of MnO surface than that of FMBO and FeOOH could be ascribed by lower pH of MnO than that of FMBO and FeOOH and this could contribute to more binding sites on MnO surface than that of FMBO and FeOOH. The higher metal ions uptake by MnO than FMBO and FeOOH could be well explained by the surface charge mechanism.

Microwave-assisted catalytic oxidation of gaseous toluene with a Cu-Mn-Ce/cordierite honeycomb catalyst

Longli Bo, Shaoyuan Sun

《化学科学与工程前沿（英文）》 2019年第13卷第2期页码 385-392 doi: 10.1007/s11705-018-1738-3

摘要： A novel Cu-Mn-Ce/cordierite honeycomb catalyst was prepared by an incipient wetness method and the catalyst was characterized. The active ingredients were present as various spinel species of Cu, Mn and Ce oxides with different valences and they were unevenly dispersed over the surface of the catalyst. The catalytic oxidation of gaseous toluene was primarily investigated using a fixed bed reactor under microwave heating in the continuous flow mode. Under the optimal conditions of 6.7 wt-% loading of the active component, a bed temperature of 200°C, a flow rate of 0.12 m ·h and an initial concentration of toluene of 1000 mg·m , the removal and mineralization efficiencies of toluene were 98% and 70%, respectively. Thus the use of the microwave effectively improved the oxidation of toluene and this is attributed to dipole polarization and hotspot effects. After four consecutive cycles (a total of 1980 min), the Cu-Mn-Ce/cordierite catalyst still exhibited excellent catalytic activity and structural stability, and the toluene removal was higher than 90%. This work demonstrates the possibility of treating volatile organic compounds in exhaust gases by microwave-assisted catalytic oxidation.

Fluoride ions adsorption from water by CaCO enhanced Mn–Fe mixed metal oxides

《化学科学与工程前沿（英文）》 2023年第17卷第2期页码 236-248 doi: 10.1007/s11705-022-2193-8

摘要： Novel CaCO₃-enhanced Mn–Fe mixed metal oxides (CMFC) were successfully prepared for the first time by a simple-green hydrothermal strategy without any surfactant or template combined with calcination process. These oxides were then employed as an adsorbent for adsorptive removal of excess fluoride ions. The adsorbent was characterized by SEM, XPS, XRD, FTIR, and BET analysis techniques. The adsorption property of CMFC toward fluoride ion was analyzed by batch experiments. In fact, CMFC exhibited adsorption capacity of 227.3 mg∙g^‒1 toward fluoride ion. Results showed that ion exchange, electrostatic attraction and chemical adsorption were the main mechanism for the adhesion of large amount of fluoride ion on the CMFC surface, and the high adsorption capacity responded to the low pH of the adsorption system. When the fluoride ion concentration was increased from 20 to 200 mg∙L^‒1, Langmuir model was more in line with experimental results. The change of fluoride ion adsorption with respect to time was accurately described by pseudo-second-order kinetics. After five cycles of use, the adsorbent still maintains a performance of 70.6% of efficiency, compared to the fresh adsorbent. Therefore, this material may act as a potential candidate for adsorbent with broad range of application prospects.

摘要： A green synthetic method using mixted solvents of di-methyl formamide(DMF) and acids instead of single DMF to synthesize metalloporphyrins(TRPPMCl) from TRPPH and MCl metallization was proposed in this paper. A series of TRPPMCl (M= Fe, Mn, Co) were synthesized through this innovative synthetic method, and these complexes were characterized with various spectroscopic techniques, including IR and UV-Vis spectroscopy. The results showed that the metallization time was markedly reduced from about 10 h to 0.5 h in contrast with the conventional synthetic methods.

Effect of K and Ca on catalytic activity of Mn-CeO

Boxiong SHEN, Lidan DENG, Jianhong CHEN

《环境科学与工程前沿（英文）》 2013年第7卷第4期页码 512-517 doi: 10.1007/s11783-013-0519-y

摘要： Mn-CeO /Ti-pillared clay (PILC) is an attractive catalyst for selective catalytic reduction of NO at low temperature because of its low cost. The poisoning of K and Ca on the catalyst of Mn-CeO /Ti-PILC is an important problem because K and Ca are always in presence in flue gas. To investigate the effect of K and Ca on the physicochemical characters of the catalysts, the techniques of NH -temperature programmed desorption (TPD), H -temperature programmed reduction (TPR), and X-ray photoelectron spectroscopy (XPS) were used to analyze the fresh and deactivated catalysts of Mn-CeO /Ti-PILC. (Ca)Mn-CeO /Ti-PILC and (K)Mn-CeO /Ti-PILC are denoted for the dopes of the catalyst of Mn-CeO /Ti-PILC with Ca and K, respectively. The activities of Mn-CeO /Ti-PILC, (Ca)Mn-CeO /Ti-PILC and (K)Mn-CeO /Ti-PILC for NH -selective catalytic reduction (SCR) reaction at low temperature were investigated. The results showed that with the dopes of K and Ca on the catalysts, the SCR activities of the catalysts decreased greatly, and K exhibited more poisoning effect than Ca. With the dopes of K and Ca, the acidity, the redox property and chemisorbed oxygen on the surfaces of the catalysts were decreased, which resulted in a decreasing in SCR activity.

Removal of elemental mercury with Mn/Mo/Ru/Al

Yongfu GUO, Naiqiang YAN, Ping LIU, Shijian YANG, Juan WANG, Zan QU

《环境科学与工程前沿（英文）》 2013年第7卷第3期页码 464-473 doi: 10.1007/s11783-012-0430-y

摘要： In this work, a catalytic membrane using Mn/Mo/Ru/Al O as the catalyst was employed to remove elemental mercury (Hg ) from flue gas at low temperature. Compared with traditional catalytic oxidation (TCO) mode, Mn/Al O membrane catalytic system had much higher removal efficiency of Hg . After the incorporation of Mo and Ru, the production of Cl from the Deacon reaction and the retainability for oxidants over Mn/Al O membrane were greatly enhanced. As a result, the oxidization of Hg over Mn/Al O membrane was obviously promoted due to incorporation of Mo and Ru. In the presence of 8 ppmv HCl, the removal efficiency of Hg by Mn/Mo/Ru/Al O membrane reached 95% at 423 K. The influence of NO and SO on Hg removal were insignificant even if 200 ppmv NO and 1000 ppmv SO were used. Moreover, compared with the TCO mode, the Mn/Mo/Ru/Al O membrane catalytic system could remarkably reduce the demanded amount of oxidants for Hg removal. Therefore, the Mn/Mo/Ru/Al O membrane catalytic system may be a promising technology for the control of Hg emission.
