Tuning the bifunctional properties of an α-Fe 2 O 3 /Fe 2 TiO 5 /Pt heterojunction photoelectrode for light-induced water oxidation and oxygen reduction activity

Alpha-Fe 2 O 3 nanorods modified with Fe 2 TiO 5 and Pt enable efficient light-driven water oxidation and the ORR, serving as a bifunctional cathode in solar Zn–air batteries with 50 h stability, low charging, and high discharging potentials.
