A novel and efficient method was used for the synthesis and photocatalytic activity of fluorine doped SrTiO3. The photocatalytic activity for nitrogen-monoxide destruction was determined by measuring the concentration of nitrogen oxide at the outlet of the reactor under the irradiation of 450 W high pressure mercury lamp. The absorption edge of the photocatalyst was determined from the onset of reflectance spectra measured by ultraviolet (UV)-VIS spectrophotometers. The results show that the number of electron-hole pairs in SrTiO3 band gap increase with the improvement in the photocatalytic activity of SrTiO3.
