【摘要】：稀土元素由于具有强碱性、氧化还原性和高配位数等性质,对于许多化学反应都表现出优异的催化性能。本综述以反应为导向,简要总结了稀土催化剂在醇类氧化脱氢、气体小分子氧化、气体小分子重整等小分子转化反应中的多相催化反应性及其结构-活性的关联关系。稀土元素在多相催化体系中可以作为直接产生催化活性的主催化剂,也可以作为分散活性成分的载体,还可以作为与活性成分发生协同作用的助催化剂。预期实验研究与理论计算的结合将对新型稀土多相催化材料的理性设计和开发提供更可靠的理论基础和实验支撑。
[Abstract]:Rare earth elements exhibit excellent catalytic properties for many chemical reactions due to their strong alkalinity, redox property and high coordination number. Based on the reaction orientation, this review briefly summarizes the multiphase catalytic reactivity and the structure-activity correlation of rare earth catalysts in small molecular conversion reactions such as oxidative dehydrogenation of alcohols, oxidation of small molecules of gases and reforming of small molecules of gases. Rare earth elements can be used as the main catalyst for the direct production of catalytic activity, as the carrier for dispersed active components, and as co-catalysts for synergistic action with the active components in the heterogeneous catalytic system. It is expected that the combination of experimental research and theoretical calculation will provide a more reliable theoretical basis and experimental support for the rational design and development of new rare earth heterogeneous catalytic materials.
