摘　　要：介绍了以有机聚合物和无机硅酸盐为载体,负载钼催化剂及其对烯烃环氧化反应催化性能的研究进展;分析了硼酸树脂、乙烯-丙烯橡胶、螯合树脂、苯并吡咯树脂、聚酰亚胺树脂、聚硅氧烷树脂、阳离子交换树脂和聚苯乙烯等有机聚合物为载体的研究情况;评价了以无机硅酸盐为载体,采用溶胶-凝胶、离子交换、同晶取代等方法负载钼对催化性能的影响;展望了多相化烯烃环氧化钼系催化剂的发展前景。The recent progress in heterogenization of homogeneous molybdenum containing catalysts used for epoxidation of olefins is reviewed. Supports for the catalysts can be divided into organic polymers and inorganic silicate. Used organic polymers as supports, we analyze and compare the conditions and problems among boracic acid group - containing resins, ethene-propylene rubbers, chelating resins, imadazole-containing resins, PI, PS, exchange resins and polystyrene; while used inorganic silicate as supports, we mainly discuss the catalytic difference among the methods, such as sol-gel, ion exchange etc. The potential applications of the supported molybdenum containing catalysts are also discussed briefly.
