Solvothermal Synthesis and Photocatalytic Properties of Nitrogen-Doped SrTiO3 Nanoparticles

الملخص EN

Perovskite-type nitrogen-doped SrTiO3 nanoparticles of 50–80 nm in diameter were successfully synthesized by the solvothermal of Ti(OC3H7)4, SrCl2⋅6H2O, and hexamethylenetetramine in KOH aqueous solution.

Nitrogen-doped SrTiO3 showed excellent photocatalytic activity under both UV and visible light irradiation, that is, the photocatalytic activity of N-doped SrTiO3 for DeNOx reaction was greater than that of SrTiO3 and commercial TiO2 (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.
