摘要
概述了纯与掺杂CeO2氧化还原性质的研究状况及CeO2单独/主成分使用方式在催化领域中的应用。由于CeO2具有优异的储放氧性能,以及吸附气体和反应中间物能与几个Ce3+同时作用,其在氧化还原、合成气生产、有机合成和有机污染物降解等反应过程中呈现出良好的催化性能,而通过恰当的掺杂往往能使之得到进一步提高。最后,结合现状对其未来研究方向进行了展望。
The redox properties of pure and doped ceria and their applications in catalysis are summarized. CeO2 plays an important role in catalyzing many reactions including redox reactions, synthesis gas production, organic synthesis, catalytic abatement of organic pollutants and so on. This arises from the ability of ceria to store or release oxygen which depends upon the conditions. Several Ce^3＋ ions interacting with reactants and intermediate retentions at the same time can make some contribution as well. Furthermore, the catalytic performance of ceria can be improved by doping other oxides. The research tendencies for promoting catalysis are proposed development of the applications of pure and doped ceria in
