摘要: TiO2 nanotubes attract much attention because of their high photoelectron-chemical and photocatalytic efficiency. But large band gap leads to a low absorption the solar light limits practical application. How obtain without any dopant possessing visible response is big challenge nowadays. Orthorhombic titanic acid (TAN) are special precursor TiO2, which possess Brunauer-Emmett-Teller (BET) surface areas strong ion exchange adsorption capacity. TAN can transform novel with amount single-electron-trapped oxygen vacancies (SETOV) during calcination, while nanotubular structure would be destroyed, BET area decrease remarkably. And interestingly, SETOV lead for this kind TiO2. Herein, glucose was penetrated into by vacuum inhalation method, dehydrate anatase undergo thermolysis completely in calcination process. As result, pure were obtained. For further improving activity, Pd nanoparticles loaded as foreign electron traps on oxidation efficiency propylene 71 % under irradiation, photostability catalyst kept over 90 % after 4 cyclic tests.
