Hematite

Hematite (α -Fe 2 O 3) is an n-type semiconductor, which encompasses the target characteristics of a photoanodic material for water oxidation.It absorbs a significant portion of visible light (thanks to its modest band gap of ca. 2.2 eV), while having a more positive valence band maximum with respect to the H 2 O/O 2 redox couple (Fig. 1 a) [1].
