Porous ultrathin WO3 nanoflake arrays as highly efficient photoanode for water splitting

•Porous ultrathin WO3 nanoflake array was prepared by one-step hydrothermal method.•The morphologies of WO3 nanoarrays can be tuned by the dosage of (NH4)2C2O4.•WO3 arrays showed remarkable photocurrent of 1.80 mA cm−2 at 1.23 V vs RHE.•The reasons for the improvement of photoelectrochemical perform...
