Synthesis of CuO _x /TiO₂ Photocatalysts with Enhanced Photocatalytic Performance.

ABSTRACT: CuO _x /TiO₂ co-photocatalysts with various Cu loading contents were synthesized by an impregnation method, and their photocatalytic activities were evaluated by photodegradation of organic pollutants under visible light illumination. The as-prepared CuO _x /TiO₂ composites exhibited a unique structure, in which CuO _x clusters with about 2-3 nm nanocrystals were uniformly distributed on the TiO₂ cube. The mesoporous Ti³⁺/TiO₂ substrate with a uniform pore structure greatly improved the uniformity of the loaded Cu, wherein Ti³⁺ acted as a reducing agent for reducing Cu²⁺ to Cu⁺ and Cu⁰. The reversible process of the Cu species between Cu
