NH3 emissions were limited strictly because of the threat for human health and sustainable development. Pt/Al2O3 Pt/CeZrO2 prepared by impregnation method. Differences in surface chemical states, reduction ability, acid properties, morphological reaction mechanisms, ammonia oxidation activity studied. It indicated that Pt species states affected different metal-support interactions. The homogeneously dispersed over exposed Pt(111) weak interactions; there even existed an obvious interface...
We present a detailed review on the mechanistic understanding and catalyst development of CeO 2 -based CO methanation catalysts. Current challenges for deeper investigations future perspectives are presented as well.
Disclosing the different structure-function relationship of promoters is vital for designing catalysts with superior performance. In this work, dispersion and location lanthanum (La), namely interact CeO2-ZrO2 (CZ) component or Al2O3 component, has been regulated by controlling pretreatment temperature CeO2-ZrO2-Al2O3 (CZA) support, then effects La structure on Pd/CZA three-way catalyst have systematically investigated to pick out doping strategy. By XRD, BET TEM tests, it found that...
Pd@Pt core–shell colloidal nanoparticles efficiently catalyse the direct oxidation of methane to methanol with high selectivity using H<sub>2</sub>O<sub>2</sub>in water.
A Pd-based catalyst prepared by a controllable two-step method of <italic>in situ</italic> reduction–oxidation showed significantly enhanced activity and selectivity.
PEG fabricates advantageous hierarchical zeolite crystals, enhancing the high-temperature and low-temperature hydrothermal stability of Cu/SAPO-34.
向Pt-Pd/CeO2-ZrO2-Al2O3（Pt-Pd/CZA）商用柴油机氧化型催化剂（DOC）中加入多孔SiO2以提高其抗硫性.使用多层涂覆法在Pt-Pd/CZA催化剂表面覆盖一层多孔SiO2,从而制得SiO2/Pt-Pd/CeO2-ZrO2-Al2O3（SiO2/Pt-Pd/CZA）抗硫DOC.并使用扫描电子显微镜（SEM）, H2程序升温还原（H2-TPR）,氮气吸脱附, X射线能谱（EDX）和热重分析（TGA）等对其进行表征. SEM结果显示, SiO2层以多孔形式均匀覆盖在催化剂表面.氮气吸脱附结果表明,所添加的SiO2的织构性质与Pt-Pd/CZA催化剂的织构性质相似,因而表面覆盖的SiO2并未明显改变Pt-Pd/CZA催化剂的比表面积和孔结构. H2-TPR结果证实表面覆盖的SiO2不影响Pt-Pd/CZA催化剂的还原性能. EDX和TGA结果说明表面覆盖SiO2可以抑制硫物种在催化剂表面的形成及累积.最终,本文所制备的SiO2/Pt-Pd/CZA催化剂在保持Pt-Pd/CZA商用DOC的高活性及耐久性的同时有效提高了其抗硫性.
The amount of Pt species was increased by the addition ascorbic acid to Pt/SiAl catalyst, which shifted temperature NH<sub>3</sub>-SCO reaction between NH<sub>3</sub> and O<sub>2</sub> a lower temperature.
The addition of Ba on the improvement hydrothermal stability over Cu/BEA: (i) stabilize dispersion Cu species and suppress formation CuO clusters; (ii) higher redox property. These two factors decide CuBa/BEA-HT rather than Cu/BEA-HT.
Compared with that of WO 3 -monoclinic (W-m), the special open structure -hexagonal (W-h) facilitates interaction between W-h and Ce as well improves acidity redox properties Ce–W-h, reflecting its excellent NH -SCR activity.
