摘　　要：随着MOFs在催化领域的蓬勃发展,已有MOFs作为催化剂用于乙烯选择性齐聚中。根据乙烯齐聚活性中心与MOFs骨架的联接方式,MOFs乙烯选择性齐聚催化剂可分为接枝型、负载型和本体型三类,分别综述了它们的应用。同时介绍了MOFs乙烯选择性齐聚遵循的两种催化机理:金属环机理和单金属机理,最后对MOFs乙烯选择性齐聚催化剂进行了总结和展望。With the rapid development of MOFs in the field of catalysis,MOFs have been used as catalysts for the selective ethylene oligomerization. In this article,according to the connection types of ethylene oligomerization active center and MOFs’ framework,the selective ethylene oligomerization MOFs catalysts are classified into three types:graft type,supported type and bulk type,which are introduced one by one. Subsequently,the two catalytic mechanisms followed by selective ethylene oligomerization over MOFs are briefly introduced:metallacyclic mechanism and Cossee-Arlman mechanism. Finally,the selective ethylene oligomerization MOFs catalysts are summarized and prospected.
