Perovskite-type nitrogen-doped SrTi O 3 nanoparticles of 50-80nm in diameter were successfully synthesized by the solvothermal of Ti (OC 3 H 7) 4, SrC l 2 6 H 2 O, and hexamethylenetetramine in KOH aqueous solution. Nitrogen-doped SrTi O 3 showed excellent photocatalytic activity under both UV and visible light irradiation, that is, the photocatalytic activity of N-doped SrTi O 3 for DeN O x reaction was greater than that of SrTi O 3 and commercial Ti O 2 (Degussa P25) in both visible light region (>510 nm) and UV light region (>290 nm). The excellent visible light photocatalytic activity of this substance was caused by generating a new band gap that absorbs visible light.
