Visible-Light-Induced Photosplitting of Water over γ′-Fe4N and γ′-Fe4N/α-Fe2O3 Nanocatalysts

The application of γ′-Fe4N, a noble-metal-free, low-cost catalyst, in the photosplitting of neat water into stoichiometric amounts of H2 and O2 under visible-light irradiation is reported for the first time. The catalyst showed optical absorption and photoluminescence emission bands in the entire vi...
