The Composite TiO-CuO Layers Formed by Electrophoretic Method for CO Gas Photoreduction.

This study demonstrates the ability to control the properties of TiO-CuO composite layers for photocatalytic applications by using a simple electrophoretic deposition method from isopropanol-based suspension. To obtain uniform layers with a controlled composition, the surfactant sodium lauryl sulfate was used, which influenced the electrophoretic mobility of the particles and the morphology of the deposited layers. The TiO-CuO composite layers with different CuO contents (1.

Photoelectron Properties and Organic Molecules Photodegradation Activity of Titania Nanotubes with CuO Nanoparticles Heat Treated in Air and Argon.

Titania is very famous photocatalyst for decomposition of organic pollutants. Its photocatalytic properties significantly depend on the morphology and chemical composition of the samples. Herein, the TiO nanotubes/CuO nanoheterostructures have been synthesized and the effect of heat treatment performed in molecular atmospheres of air and argon on their photoelectrochemical and photocatalytic properties has been studied.

Anodic TiOnanotube arrays for photocatalytic COconversion: comparative photocatalysis and EPR study.

Titania (TiO) is a widely used semiconductor for the photocatalytic decomposition of organic impurities in air, water and the conversion of COinto hydrocarbon fuel precursors. TiOin the form of nanotubes arrays is the most attractive for practical use because of the morphological advantages providing more favorable diffusion of photocatalytic reaction products and a low recombination rate of photogenerated electrons and holes. We have carried out a comparative study of the photocatalytic activity of gas-phase conversion of COto hydrocarbon products and the defect properties of multi-walled and single-walled arrays of TiOnanotubes.
