Reduction of CO2 with H2O on TiO2(100) and TiO2(110) Single Crystals under UV-irradiation

Abstract
The reduction of CO2 with H2O was investigated on the single crystals of TiO2(100) and TiO2(110); the former TiO2(100) exhibiting a higher efficiency in the formation of CH4 and CH3OH than TiO2(110). Measurements of the intermediate species formed on the TiO2(100) single crystal were carried out using a high resolution electron energy loss spectroscopy (HREELS).
