Abstract

calcination temperature, and doping with nitrogen on the morphology, crystallinity, chemical composition, and photocatalytic acivity of SrTiO3 was studied. Heating the as-prepared SrTiO3 to 700 degrees C for extended time leads to a decrease in surface area and catalytic activity. lonothermal prepared SrTiO3 exhibits a higher activity than sonochemically prepared one without co-catalyst due to a synergistic effect of anatase which is present in small amount as a by-phase. After photodeposition of Rh, however, the activity is lower than that of the sonochemically prepared SrTiO3. Nitrogen-doped SrTiO3 showed photocatalytic acivity under visible light irradiation.
