    Abstract

    In order to overcome the intrinsic drawback of pristine g-C3N4, we demonstrate a simple thermal oxidation exfoliation-photodeposition technique to fabricate a Ag/graphene-like g-C3N4 (Ag/G-g-C3N4) photocatalyst. It was revealed that the monodispersed Ag nanoparticles were well dispersed on the surface of graphene-like g-C3N4 (G-g-C3N4). The Ag/G-g-C3N4 displayed an enhanced photocatalytic activity for methylene blue degradation and the degradation rate was 10 times higher than that of pristine g-C3N4 under visible light irradiation. The enhancement of photocatalytic activity could be attributed to the surface plasmon resonance effect of Ag and large surface area (189.9 m2 g−1) of G-g-C3N4, which improve the visible light absorption ability and provide abundant reactive sites as well as promoting photogenerated electron-hole pair separation.
