Abstract

Abstract The optical and photoelectrochemical properties of ordered mesoporous α-LiFe5O8 thin films have been investigated. These sol?gel thin films exhibit a complex band structure, indicating a band gap of 2.45?eV, with additional absorption in the visible region up to ?=600?nm. Mott?Schottky plots reveal their applicability as photoanodes for water splitting (as they are n-type semiconductors) and photoelectrochemical tests show good performance for water oxidation.
