英文摘要	The advancement of photoelectrochemical water splitting oxygen evolution technology is the key to improving the solar-hydrogen conversion efficiency. The theoretically highly active hematite-based photoanode still requires modification from inside to outside to conquer ultrafast carrier recombination and a high reaction barrier. Herein, we report a uniform and ultrathin cocatalyst with coordinated tannic acid, Ni, Fe, and Co (TA-NFC), for enhancing photoelectrochemical performance of the Fdoped Fe2O3 nanorod (NR) photoanode. The F-doping in the structure fulfills more carrier density and lower charge transfer resistance for accelerating photogenerated electron and hole separation. Furthermore, the TA-NFC cocatalyst on the surface assists hole injection and supports faster water oxidation kinetic. Ultimately, the photocurrent density of F-Fe2O3@TA-NFC NRs sharply increased up to 3.02 mA/cm(2) at 1.23 V versus RHE, and the applied-bias photon-to-current efficiency reached 0.33% maximum at low bias. This work may supply a novel and promising design scheme for improving the intrinsic photoelectrochemical activity of semiconductor-based photoanodes.
