英文摘要	Nickel tin composite oxides decorated graphene nanohybrid (NiSn_xO_y/G) cocatalyst was synthesized by in-situ chemical deposition and followed photoreduction reaction. The structure of NiSn_xO_y/G was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity of NiSn_xO_y/G sensitized by Eosin Y (EY) for hydrogen evolution were evaluated under visible light irradiation (λ ＞ 420 nm) using triethanolamine (TEOA) as sacrificial donor. The results indicated that the large amounts of NiSn_xO_y adhered on the surface of graphene sheet as active sites for hydrogen production. NiSn_xO_y/G showed higher photocatalytic performance than Ni/G under visible light irradiation (λ ≥ 420 nm) due to the higher photocatalytic activities of NiSn_xO_y and the electron transfer function of graphene sheets. The highest apparent quantum efficiency (AQE) of 36.2% over EY-NiSn_xO_y/G was achieved at 430 nm.
