摘　　要：本文总结了有关氧化铈的催化作用,指出氧化铈具有贮氧性,可改善催化剂的还原性及分散度等特性,给出了氧化铈与主剂、载体间及在催化过程中的几种作用形成;展示了氧化铈在一氧化碳中变反应中的应用,给出了有关研究结果,并提出了今后的研究方向。In this paper, the application of C_0O_2 in Catalytic reactions were introduced, especially in water-gas shift reaction. A new kind of chromia-promoted magnetite catalyst—SXB has been studied, in which some C_0O_2 was added to replace partly Cr_2O_3. It's good catalytic properties were given out by study of TPD, TPR, TPO, TPSSR, TG-DTG, TG-DTA, XRD, SEM and BET. The direction of further study was also pointed out.
