Organic-inorganic　hybrid　semiconductors　have　good　prospects　in　photocatalysis　for　the　enhanced　light　absorption　and　photo-generated　charges　separation.　Organic　semiconductor　tetrathiafulvalene　(TTF)　shows　excellent　optical　and　electrical　properties,　widely　studied　in　photoelectric　materials　and　devices.　Herein,　TTF　modified　ZnS　with　four　different　morphologies　were　obtained,　and　the　effect　of　morphology　for　the　photo-catalytic　H2　evolution　performance　was　explored.　The　photocatalytic　performance　is　superior　when　2　wt%　TTF　is　combined　with　98　wt%　ZnS　spheres,　exhibiting　the　best　photocatalytic　hydrogen　production　capability,　reaching　4221　mu　mol　g-1　h-1.The　tight　contact　and　interaction　between　TTF　and　ZnS　facilitate　the　transport　of　photo-generated　carriers　and　minimized　the　recombination　of　hole-electron　pairs,　thereby　enhancing　the　photo-catalytic　performance.　This　work　demonstrates　that　the　tight　interface　connection　between　organic　and　inorganic　components　is　a　key　to　constructing　high　performance　semiconductor　photocatalysts　for　hydrogen　production.
