Nanocomposites　of　BiPO4　and　reduced　graphene　oxide　(BiPO4/RGO)　synthesized　by　hydrothermal　method,　hydrazine　reduction,　and　UV-assisted　photoreduction　method　were　studied　as　photocatalysts　for　hydrogen　evolution　from　ethanol　aqueous　solution　under　irradiation.　The　incorporation　of　RGO　into　BiPO4　significantly　enhanced　the　photocatalytic　activity　for　H-2　evolution,　and　the　photocatalytic　activity　increases　in　the　order　of　BiPO4/RGO-hydrothermal　＞　BiPO4/RGO-photoreduction　＞　BiPO4/RGO-hydrazine.　The　optimum　proportion　of　GO　is　2　wt%　for　all　the　samples　prepared　by　different　methods.　The　rate　of　H2　production　calculated　for　BiPO4/RGO-hydrothermal　(with　2　wt%　GO)　nanocomposite　was　about　306　mu　mol/h/g,　which　was　almost　2　times　as　high　as　that　for　bare　BiPO4.　The　XRD,　Raman　and　XPS　characterization　suggested　that　the　original　GO　was　successfully　reduced　to　RGO.　The　more　intimate　contact　between　BiPO4　and　RGO,　the　higher　photocurrent　responses　and　the　higher　reduction　degree　of　RGO　was　consistent　with　the　higher　photocatalytic　performance.　Copyright　(C)　2014,　Hydrogen　Energy　Publications,　LLC.　Published　by　Elsevier　Ltd.　All　rights　reserved.
