Photocatalytic Activity of Cu–TiO₂ Nanopowder Under UVA and Sunlight Illumination: Influence of Composition and Calcination Temperature on Charge Transfer

Cu–TiO₂ nanoparticles of a broad range of compositions with 0, 0.002, 0.005, 0.02, 0.05, 0.2, 0.5, 1.0, 2.0, 3.0, 5.0, 7.0 and 10.0 mol% Cu were synthesized via the sol–gel method using copper (II) acetate and titanium tetraisopropoxide (TTIP) precursors at a low hydrolysis ratio of H = 1...
