Abstract Composites of BiOCl-RGO were synthesized via a two-step hydrothermal method. Firstly plain BiOCl was synthesized in the mixed solution of ethylene glycol and deionized water, the acquired nanosphere-like BiOCl of about 400 nm in diameter composed of many nanosheets. Then the RGO carrier was deposited onto the plain BiOCl to prepare BiOCl-RGO nanocomposites. The composites were characterized by Raman spectroscopy, XRD, XPS, SEM and TEM. The photocatalytic property of the composites was evaluated by degrading methyl orange. The results show that the temperature of hydrothermal process significantly affects the photocatalytic property of the composites. The composite of BiOCl -graphene prepared at 140°C shows the highest photocatalytic performance.
