Hollow　MoS2/g-C3N4　hybrids　were　obtained　through　a　combination　route　of　hard-templating　technique　and　impregnation-sulfidation　method.　The　physicochemical,　optical/electric　and　electrocatalytic　properties　of　the　obtained　samples　were　characterized　by　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　X-ray　photoelectron　spectroscopy　(XPS),　UV-vis　diffuse　reflectance　spectroscopy,　photoluminescence　(PL)　spectroscopy　and　electrochemical　measurement.　Their　photocatalytic　activities　were　evaluated　by　H-2　production　from　lactic　acid　aqueous　solution　with　＂visible　light　irradiation.　The　results　showed　that　MoS2/HCNS　nanojunctions　exhibited　enhanced　photocatalytic　H-2　production,　which　could　be　attributed　to　the　thin　layered　junctions　formed　between　MoS2　and　HCNS　for　efficient　charge　separation　and　the　active　sites　provided　by　MoS2　for　H-2　production　at　lower　over　potentials.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
