Influence of the Structure of Hydrothermal-Synthesized TiO2 Nanowires Formed by Annealing on the Photocatalytic Reduction of CO2 in H2O Vapor
The present study investigates the photocatalytic properties of hydrothermally synthesized TiO<sub>2</sub> nanowires (NWs) for CO<sub>2</sub> reduction in H<sub>2</sub>O vapor. It has been demonstrated that TiO<sub>2</sub> NWs, thermally treated at 500-700 °C, demonstrate an almost tenfold higher yield of products compared to the known commercial powder TiO<sub>2</sub> P25. It has been found that the best material is a combination of anatase, TiO<sub>2</sub>-B and rutile. The product yield increases with increasing heat treatment temperature of TiO<sub>2</sub> NWs. This is associated with an increase in the degree of crystallinity of the material. It is shown that the best product yield of the CO<sub>2</sub> reduction in H<sub>2</sub>O vapor is achieved when the TiO<sub>2</sub> NW photocatalyst is heated to 100 °C.
