The Photoelectrochemical Activity of Titanium Dioxide Nanosized Films in the Visible Spectral Region

From solutions of organic precursors, nanosized films of titanium dioxide with photoelectrochemical activity in the visible region are obtained. A possibility of photoelectrochemical oxidation of a number of organic compounds under illumination with monochromatic light at a wavelength of 464 nm is demonstrated, which may be due to a decrease in the n-TiO2 band-gap energy to 2.7 eV.
