Photocatalytic water splitting with cobalt oxide / titania / palladium nanocomposite catalysts

摘要

Photocatalysts and methods of using them to produce hydrogen and oxygen from water are disclosed. The photocatalysts include photoactive titanium dioxide loaded at 0.5 wt% to 4 wt% of a hole-trapping material comprising cobalt oxide, and 0.1 wt% to 1 wt% palladium (Pd) and / or a Pd / Co alloy.
