摘　　要：The convertion of solar energy into hydrogen energy with high energy density by photocatalysis is a green and eco-friendly avenue to solve the energy crisis and environmental pollution issues 1,2.Unfortunately,most photocatalysts usually suffer from the rapid quenching of photogenerated carriers and depressed interfacial H_(2)-generation dynamics 3,4.To overcome the above shortcomings,cocatalysts are widely employed to promote the separation of photocarriers and to create active sites for surface catalytic reactions 5.For a superb cocatalyst,its active sites usually play a key role in the overall performance of photocatalytic H_(2) evolution because the active sites can not only provide a large number of adsorption centers to enrich H+,but also present an outstanding catalytic efficiency to convert H+into H_(2) by reducing its reaction overpotential 6.Thus,the active-site number and efficiency of cocatalysts should be maximized as much as possible to greatly boost the cocatalytic H2-evolution activity by photocatalysis.
