摘　　要：综述了近年来对金属有机催化剂甲基三氧化铼负载化方法的研究进展。介绍了甲基三氧化铼通过物理吸附或化学吸附负载在不同载体材料上的方法及负载后作为非均相催化剂在烯烃环氧化、硅烷氧化、烯烃复分解和Bacyer-Villiger等多种反应中的应用,同时指出与单纯使用甲基三氧化铼进行的均相催化反应过程相比,通过物理吸附法负载后的催化剂在循环催化反应中,催化剂不可避免流失问题,以及通过化学吸附法负载后导致催化剂的失活问题,并对今后的发展趋势进行展望。The progress in the immobilization of methyhrioxorhenium in recent years was reviewed. The immobilization methods of methyltrioxorhenium on different supports via physical adsorption or chemical adsorption and the application of the immobilized methyltrioxorhenium as the hetereogenous catalyst for many organic reactions, such as olefin epoxidtion, silieane oxidation, olefin metathesis and Baeyer-Viliger reactions were introduced. It was pointed out that compared with homogeneous process catalyzed by meth- yhrioxorhenium, the loss of the catalyst immobilized by physical adsorption method could not be avoided, while immobilization by chemical adsorption method resulted in deactivation of the catalyst. The develop- ment trend of immobilization in future was outlined.
