Photocatalytic water splitting over CeO2/Fe2O3/Ver photocatalysts

Martin Reli et al.

Summary: The study found that Fe8Ce2 is the most active photocatalyst, both in standalone powder form and attached on vermiculite, for hydrogen production via water splitting. The photocatalytic activity of Fe2O3/CeO2 photocatalysts is controlled by intrinsic photocatalytic properties of the oxides and the specific surface area of the composite. The formation of heterojunction Type I with bent bands effectively inhibits the recombination of photogenerated charge carriers.
