Effect of Surface Acidity of Codoped C,S-TiO2 on Their Photocatalytic Properties in the Hydrogen Evolution and Ethanol Oxidation Processes
Codoped C,S-TiO2 nanostructures with similar structural and dimensional characteristics and different surface acidity have been obtained using a hydrothermal sol–gel method in the presence thiourea or sulfuric acid. It is established that C,S-TiO2 obtained in the presence of H2SO4 are characterized with acidity of 0.45 mmol/g that results in a high photocatalytic activity in the process of ethanol oxidation. It is shown that C,S-TiO2 obtained in the presence of thiourea, exhibits photocatalytic activity in the reaction of hydrogen evolution under UV and visible light irradiation, which increases with surface acidity decreasing.
