Abstract：

Mesoporous　graphitic$　carbon　nitride　(mpg-CN)　was　loaded　with　WS2　via　an　impregnation-sulfidation　approach.　The　resultant　surface　heterojunctions　between　WS2　and　mpg-CN　were　evidently　confirmed　with　transmission　electron　microscopy　(TEM)　and　X-ray　photoelectron　spectroscopy　(XPS).　Photocatalytic　H2　production　on　WS2/mpg-CN　under　visible　light　(λ>420nm)　shows　that　WS2　plays　an　important　role　in　catalyzing　H2　production.　The　rate　of　hydrogen　evolution　reaches　an　optimum　when　the　loading　amount　of　WS2　is　about　0.3at.%.　Combined　with　the　physicochemical　and　electrocatalytic　properties　of　WS2/mpg-CN,　it　can　be　concluded　that　the　enhanced　photocatalytic　H2　production　activity　on　WS2/mpg-CN　is　mainly　attributed　to　the　thin　layered　junctions　formed　between　WS2　and　mpg-CN　and　the　great　performance　of　WS2　as　a　cocatalyst　in　H2　evolution　reaction.　©　2014　Elsevier　B.V.
