Nitrogen-doped TiO2 (N-dope TiO2) shows photocatalytic activity even under visible light irradiation and various methods doping nitrogen atom into TiO2 crystalline structure have been reported. N-dope TiO2 particles keeping anatase crystal structure were prepared. Anatase TiO2 particles were mixed with Mg powders (reductant) and sodium azide (nitrogen source) and calcined at 600°C. The obtained particles had the onset of absorption around 500 nm while it kept anatase crystalline structure. These samples had slight photocatalytic activity against oxidation of 2-propanol under visible light irradiation. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
