Exploring　the　morphology-property　relationship　is　an　important　role　in　addressing　the　mechanism　of　hydrogen　production.　In　this　work,　WO3　photocatalysts　with　different　morphology　were　prepared　via　a　solvothermal　method.　Our　first　prepared　porous　WO3　with　the　exposed　(100)　crystal　plane,　the　WO3　porous　nano　disk　demonstrates　a　better　photocatalytic　activity,　which　is　higher　than　the　WO3　nanorod,　WO3　nanoflower　and　WO3　nano　block.　Further　characterizations　indicate　the　WO3　porous　nano　disk　exhibits　high　absorption　capacity　and　active　lattice　structure.　Meanwhile,　with　the　introduction　of　non-noble　metal　Ni　as　the　co-catalyst,　the　photocatalytic　H-2　evolution　was　enhanced.　This　work　reveals　the　importance　of　regulating　surface　atomic　configuration　and　catalytic　active　sites,　opens　a　new　avenue　for　the　development　of　solar-driven　water　splitting.
