摘要：

FeNiOOH-decorated hematite photoanode has been prepared by a facile electrodeposition method, with a significant cathodic shift of the onset potential (up to 190 mV) compared to the pristine sample. Synchrotron radiation based techniques have been used to identify the composition in the catalyst indicating the presence of FeOOH and NiOOH (FeNiOOH). The enhanced performance can be attributed to the better oxidation evolution reaction kinetics with the FeNiOOH cocatalyst. The FeNiOOH-decorated hematite is very stable in a long time. Moreover, the cocatalyst can be well coupled to the Pt-modified hematite photoanode achieving a high photocurrent of 2.21 mA cm^-2 at 1.23 V vs. RHE. The good catalytic property and the facile preparation method suggest that the decoration of FeNiOOH is a favorable strategy to improve the performance of hematite.
