| 英文摘要 | a series of self-assembled polyoxometalate (pom) catalysts were directly immobilized into layered double hydroxides (ldh) by a selective ion-exchange method. sandwich-type pom species are found to be more favorable than keggin-type pom for the direct immobilization in ldh. because strict ph controlling is not needed and the ldh hosts can be kept intact. the resulting ldh-pom catalysts were evaluated in the epoxidation of allylic alcohols with aqueous h2o2 as the oxidant without using organic solvent. the heterogeneous ldh-pom catalysts show much higher epoxide selectivity than the corresponding homogeneous na-pom catalysts, which can be attributed to the beneficial effect of basic ldh host on the suppression of the acid-catalyzed epoxide hydrolysis. the cooperation between the pom guest and the ldh host can achieve up to 99% selectivity of epoxide, 95% h2o2 efficiency and 37200 h(-1) tof without the need of base additives and ph controlling, and the host-guest catalysts can be readily recycled with no apparent loss of catalytic performance.
