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.

共掺杂C,S-TiO2表面酸性对其析氢和乙醇氧化过程光催化性能的影响

在硫脲或硫酸存在下，采用水热溶胶-凝胶法获得了具有相似结构和尺寸特征以及不同表面酸度的共掺杂C,S-TiO _{2纳米结构。}确定在H ₂ SO ₄存在下获得的C,S-TiO _{2 的}酸度为0.45 mmol/g，这导致在乙醇氧化过程中具有高光催化活性。结果表明，硫脲存在下得到的C,S-TiO _{2在紫外和可见光照射下的析氢反应中表现出光催化活性，且随着表面酸度的降低而增加。}
