The optical and photoelectrochemical properties of ordered mesoporous α‐LiFe 5 O 8 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 λ =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.
