A beta-Fe2O3 nanoparticle-assembled film for photoelectrochemical water splitting

Since Fe₂O₃ is a promising photoanode material for water splitting, it has attracted much attention, while other phases of ferric oxide are ignored. Here, β-Fe₂O₃ was used as a photoanode material for solar water splitting, and a solar photocurrent of ca. 0.12 mA cm² at 1.6 V_RHE was observed.
