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 H2 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.
