摘　　要：烯烃歧化是一种通过C—C键断裂重排生成新的烯烃分子的反应,可以根据市场需求灵活调控目标产物的生成,是烃类资源高效转化利用的一条重要途径。与均相催化剂相比,烯烃歧化多相催化体系具有易制备、分离简单、可循环再生的优点,在大规模化工生产中具有很好的应用前景。从催化剂的制备方法、应用反应类型及反应机理方面,重点阐述了多相Mo基催化剂催化烯烃歧化反应的研究现状和最新进展。Olefin metathesis, which is one of the most important C-C bond formation reactions, has received increasing attention. By the olefin metathesis the stocks of olefins upon the market demanding can be regulated at low energy and environmental cost which also provides a new way for the production of valued-added olefins. Heterogeneous catalysts for metathesis reactions are of further interest due to their ease of separation, good persistence and recyclahility. This review focuses on the development of Mo based heterogeneous catalysts and its application in olefin metathesis reaction. Related new preparation methods, reaction types and working mechanism are summarized in detail.
