Influence of the Structure of Hydrothermal-Synthesized TiO Nanowires Formed by Annealing on the Photocatalytic Reduction of CO in HO Vapor.

The present study investigates the photocatalytic properties of hydrothermally synthesized TiO nanowires (NWs) for CO reduction in HO vapor. It has been demonstrated that TiO NWs, thermally treated at 500-700 °C, demonstrate an almost tenfold higher yield of products compared to the known commercial powder TiO P25. It has been found that the best material is a combination of anatase, TiO-B and rutile.

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.
