    • Abstract


      In this research, strontium titanate (SrTiO₃) nanoparticles were synthesised using an ultrasonic method, then were doped with Pt using a photo-assisted deposition method to form Pt/SrTiO₃ nanoparticles.SrTiO₃ and Pt/SrTiO₃ nanoparticles were characterized by XRD, XPS, TEM, BET surface area UV–Vis and PL techniques in order to explore their chemical and physical properties. The visible light irradiation photocatalyticperformances of SrTiO₃ nanoparticles and Pt/SrTiO₃ nanoparticles for photocatalytic oxidation of cyclohexane was investigated, and the results revealed that platinum was doped onto the SrTiO₃ nanoparticles surfaces as metallic platinum, and the weight percent of doped platinum greatly affected the band gap, and the 1.5wt% Pt/SrTiO₃ nanoparticles showed the highest photocatalytic activity due to the low band gap. The stability of thePt/SrTiO₃ nanoparticles for the photocatalytic oxidation of cyclohexane was examined and the results revealed that the Pt/SrTiO₃ nanoparticles could be used five times without losing their efficiency.
