英文摘要	Dysprosium-doped titanium dioxide-decorated graphene oxide (GO/Dy3+-TiO2) was prepared with graphene oxide (GO), tetrabutyl titanate and dysprosium nitrate as precursors using an in-situ method of synthesis via a citric acid chelating sol-gel step. Afterwards, dysprosium doped titanium dioxide and reduced graphene oxide (rGO/Dy3+-TiO2) composite photocatalysts were obtained via a sodium borohydride reduction method. The composite materials were characterized by X-ray diffraction, transmission electron microscopy, Raman spectroscopy and photoluminescence spectroscopy, respectively. The effect of GO on the crystal structure of TiO2, the lifetime of photogenerated carriers, and the morphology and photocatalytic activity of composite photocatalysts was investigated. The results show that Dy3+-TiO2 nanoparticles with anatase phase are well dispersed on the surface of the rGO sheets. The introduction of GO inhibits the grain growth of TiO2 and the phase transformation from anatase to rutile. The photocatalytic activity of rGO/Dy3+-TiO2 is greater than that of Dy3+-TiO2. © 2016, Editorial Department of Journal of the Chinese Ceramic Society. All right reserved.
