Description
Electron spin resonance spectroscopy is used to study the effects of illumination and changes in temperature on spin centers in nanocrystalline anatase powders synthesized by sol-gel methods with various complexing agents. A correlation between the concentration of oxygen radicals at the surface and the rate of photocatalytic decomposition of organic compounds in the presence of TiO2 is observed. It is shown that the concentration of centers active in the electron spin resonance spectra can be used for monitoring the photocatalytic activity of TiO2.
