Abstract：A series of Keggin type H3 SiMo12 O40/GO-SiO2 composites was prepared by sol-gel method. The structures and compositions of the materials were characterized by FT-IR,Raman,XRD,and TG-DTA,indicating that the SiMo12 clusters were chemically attached to the GO-SiO2 supports,and the prima-ry Keggin structure remained intact in the as-synthesized composites.The catalytic activity of the SiMo12/GO-SiO2 composites was evaluated by the epoxidation reaction of alkenes.
