Photocorrosion Inhibition and Enhancement of Photocatalytic Activity for ZnO via Hybridization with C60

C-60 molecules with monomolecular layer state dispersed on the surface of DO and formed the hybridized interacton between ZnO and C-60 center dot C-60-hybridized ZnO photocatalyst showed enhanced photocatalytic activity for the degradation of the organic dye and the photocorrosion of ZnO was successfully inhibited by the hybridization of C60 molecules. The photocorrosion inhibition of ZnO by C-60 molecule could be attributed to the reduced activation of surface oxygen atom. The enhanced photocatalytic activity for C-60-hybridized ZnO was originated from the high migrabon efficiency of photoinduced electrons on the interface of C-60 and ZnO, which was produced by the interacton of C-60 and ZnO with a conjugative pi-system. The enhancement degree of photocatalytic activity was strongly depended on the coverage of C-60 molecules on the surface of ZnO nanoparficles, and the optimum hybridizabon effect was found at a weight ratio of 1.5% (C-60/ZnO) The hybridization of C-60 with semiconductors could be used to improve the photocatalytic activity as well as the photostability.
