Complexes of the type (L–L)MoO(O2)2 heterogenized on phenylene-bridged mesoporous organosilicas show a 10-fold increase in catalytic activity and a high stability in liquid phase epoxidation reactions, with H2O2 as the oxidant, compared to the corresponding MCM-41-derived systems.
类型为(L–L)MoO(O2)2的复合物在苯烯桥接的介孔有机硅材料上被异质化,相比于相应的MCM-41衍生体系,在液相环氧化反应中,以H2O2作为氧化剂时,其催化活性提高了10倍,并且表现出较高的稳定性。
