Zusammenfassung: | C... molecules with monomolecular layer state dispersed on the surface of ZnO and formed the hybridized interaction between ZnO and C... C...-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 C... molecules. The photocorrosion inhibition of ZnO by C... molecule could be attributed to the reduced activation of surface oxygen atom. The enhanced photocatalytic activity for C...-hybridized ZnO was originated from the high migration efficiency of photoinduced electrons on the interface of C... and ZnO, which was produced by the interaction of C... and ZnO with a conjugative ...-system. The enhancement degree of photocatalytic activity was strongly depended on the coverage of C... molecules on the surface of ZnO nanoparticles, and the optimum hybridization effect was found at a weight ratio of 1.5% (C.../ZnO). The hybridization of C... with semiconductors could be used to improve the photocatalytic activity as well as the photostability. (ProQuest: ... denotes formulae/symbols omitted.) |
