Selective epoxidation of olefins by hydrogen peroxide in water using a polyoxometalate catalyst supported on chemically modified hydrophobic mesoporous silica gel

A new heterogeneous catalyst prepared by immobilisation of polyoxometalates on chemically modified hydrophobic mesoporous silica gel has been successfully applied to the selective epoxidation of olefins with 15% aqueous H2O2 without the use of organic solvent.
