摘　　要：对稀土铈和钼酸铋不同比例的催化剂下，丙烯选择催化呈现的比较复杂的动力学行为，给出统一合理的机理。指出催化剂表面活性中心晶格氧经历吸附原子态氧，但不生成分子态氧。并拟定不同比例条件下，丙烯氧化的反应机理，很好地解释了实验结果。The result of selective oxidation of propylene exhibits comparatively complex behaviors,at different BiCe ratios of the catalyst. An unified reaction mechanism is presented in this article.It is shown that the surface active center of catalyst changes from the latticeoxygen to the atomicstate, not to the molecular state.The reaction mechanism proposed interprets the experimental results satisfactorily.
