Dual promotional effect of Cu _x O clusters grown with atomic layer deposition on TiO₂ for photocatalytic hydrogen production.

ABSTRACT: The promotional effects on photocatalytic hydrogen production of Cu _x O clusters deposited using atomic layer deposition (ALD) on P25 TiO₂ are presented. The structural and surface chemistry study of Cu _x O/TiO₂ samples, along with first principles density functional theory simulations, reveal the strong interaction of ALD deposited Cu _x O with TiO₂, leading to the stabilization of Cu _x O clusters on the surface; it also demonstrated substantial reduction of Ti⁴⁺ to Ti³⁺ on the surface of Cu _x O/TiO₂ samples after Cu _x O ALD. The Cu _x O/TiO₂ photocatalysts showed remarkable improvement in h
