摘要	Dysprosium-doped titanium dioxide-decorated graphene oxide (GO/D_y~(3+)-TiO_2) 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/D_y~(3+)-TiO_2) 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 TiO_2, the lifetime of photogenerated carriers, and the morphology and photocatalytic activity of composite photocatalysts was investigated. The results show that D_y~(3+)-TiO_2 nanoparticles with anatase phase are well dispersed on the surface of the rGO sheets. The introduction of GO inhibits the grain growth of TiO_2 and the phase transformation from anatase to rutile. The photocatalytic activity of rGO/D_y~(3+)-TiO_2 is greater than that of D_y~(3+)-TiO_2.
