▎ 摘　　要

We have described the room temperature synthesis of a graphene oxide-molybdenum oxo-bis(dithiolene) ([Ph4P](2)[MoO(S2C2(CN)(2))(2)]) composite (GO-Mo). The ionic and non-covalent interactions between the Mo complex and the GO surface aided the formation of a layered GO-Mo structure, employing GO as a template. GO-Mo has been characterized using electron microscopy (FESEM and TEM), Fourier transform infrared (FTIR) spectroscopy, powder X-ray diffraction (PXRD), and X-ray photoelectron spectroscopy (XPS). GO-Mo showed remarkable activity (>90%) for the degradation of Rhodamine B and Rose Bengal dyes in aqueous solution under visible light irradiation (rate of degradation 0.090 and 0.088 min(-1) respectively) without any sacrificial agent and precious metal co-catalysts. The kinetics of the degradation have been followed using UV-Vis spectroscopy. We ascribe the superior photocatalytic efficiency of GO-Mo to its layered structure, which could adsorb the dye on the GO-Mo surface and thus facilitate the electron transfer during photo-irradiation. The catalyst was easily separable post water treatment and could be reused up to six times.
