摘要：
The mechanism for the photooxidation of NO over hydrogen plasma-treated TiO2 under visible light irradiation was studied by in situ Fourier transform infrared spectroscopy. It was found that the oxidation of NO over plasma-treated TiO2 under visible light proceeded consecutively as NO --> NO2- --> NO3-, where the oxidation process of NO2- to NO3- was newly created by irradiation of visible light.
