中文摘要：

本文以石墨烯氧化物（GO）和硫代钼酸铵（（NH4）2MoS4）为前体，曙红（EY）和三乙醇胺（TEOA）为光敏单元和电子牺牲体，通过一种环境友好的光还原方法原位制备了石墨烯一硫化钼（RGO-MoSx）产氢催化剂。RGO-MoSx表现出高效的催化产氢活性，石墨烯的引入使其催化产氢效率提高至原来的2．10倍。通过傅里叶红外光谱（FTIR）、拉曼光谱（Raman）、透射电子显微镜（TEM）和X射线光电子能谱（XPS）表征，证实了RGO-MoSx的组成、结构及形貌特征。

英文摘要：

Hybrid hydrogen evolution catalyst of RGO-MoSx was prepared by an in situ photoreduction method, in which GO （graphene oxide） and （NH4）2 MoS4 （ammonium thiomolybdate） was employed as the precursor, Eosin Y （EY） as the photosensitizer, and TEOA （triethanolamine） as the sacrificial electron donor. 2.10 timest enhancement in photocatalytic hydrogen evolution was observed due to the introduction of GO. Raman spectra, FTIR spectra, TEM, SEM, and XPS were used to characterize the composition, structure and morphology of RGO-MoSx catalyst.
