Interface Engineering of CoFe-LDH Modified Ti: α-Fe₂O₃ Photoanode for Enhanced Photoelectrochemical Water Oxidation.

ABSTRACT: Effectively regulating and promoting the charge separation and transfer of photoanodes is a key and challenging aspect of photoelectrochemical (PEC) water oxidation. Herein, a Ti-doped hematite photoanode with a CoFe-LDH cocatalyst loaded on the surface was prepared through a series of processes, including hydrothermal treatment, annealing and electrodeposition. The prepared CoFe-LDH/Ti:α-Fe₂O₃ photoanode exhibited an outstanding photocurrent density of 3.06 mA/cm² at 1.23 V_RHE, which is five times higher than that of α-Fe₂O₃ alone. CoFe-LDH modification and Ti doping on hematite can boost the surface charge transfer efficiency, which is mainly attributed to the interface interaction between CoFe-LDH and Ti:α-Fe₂O
