Synthesis and Characterization of SnO₂/N-Doped TiO₂ Nanoparticles

Abstract:

SnO₂/N – doped TiO₂ photocatalysts were prepared by the modified sol-gel method. Tin tetrachloride pentahydrate, urea and polyethylene glycol were used as precursors and calcined at a temperature of 500 °C for 2 h for making powders. Different interstitial amount of nitrogen additives were in range of 0 to 40 mol%N. The XRD patterns show the TiO₂ nanocomposites are anatase phase. It was also apparent that doped nitrogen has an effect on crystallite size and band gap energy on absorbed light wavelength leading of enhancement of photocatalytic activity of TiO₂ composite nanoparticles. The result showed 20 mol%N of TiO₂ nanocomposites exhibited high photocatalytic activity, redshift in adsorption edge and a small crystallite size.
