  • Single–phase perovskite strontium titanate SrTiO3 was synthesized from strontium nitrate and tetra–n–butyl orthotitanate using sol–gel method with various calcined temperature from 600–900 °C. Prepared catalysts were characterized by X–ray diffraction (XRD), scanning electron microscope (SEM), ultraviolet–visible diffuse reflection spectroscopy (UV–DRS). The result showed that SrTiO3, which was synthesized at 700 °C in 6 hours, possessed the efficiency of 59.9 % regarding photocatalytic activity for the 10 ppm methylene blue degradation under visible (λ = 390 ÷ 750 nm). Furthermore, the results indicated that the doping of M (M = Mo, V) into the structure SrTiO3(SrTi1-(x+y)MoxVyO3) in...
