Preparation, Characterization And Photoelectrochemical Activities Of Cu-Tio_2/Ito Films, Dong Shu
Journal of Electrochemistry
Cu-TiO_(2)/ITO films were prepared by direct photo-reduction deposition of Cu~(2+) on TiO_(2)/ITO films. The nanocomposite films were characterized by UV-vis diffuse reflectance spectra (DRS), XRD spectra, Scanning Electron Microscope (SEM) technology, and photovoltage measurement. The feasibility of improving the photocatalytic activity of TiO_(2) film by combining the modification of Cu nanoparticles with the application of anodic bias was investigated. The experimental results showed that the deposited Cu has an apparent enhancement effect with respect to suppressing the recombination between the photogenerated charge carriers and enhancing the photocatalytic oxidation of formic acid. The combination could promote the photocatalytic oxidation of formic …
