Heterojunction of CuO nanoclusters with TiO2 for photo-oxidation of organic compounds and for hydrogen production

"Heterojunctions of small CuO nanoclusters (synthesized by radiolysis) with TiO2 (commercial P25) induced a photocatalytic activity under visible light irradiation in a wide range of wavelengths due to the narrow bandgap of CuO nanoclusters of around 1.7 eV. The optical, chemical, and electrica...
