Preparation method of photocatalyst, using TiCl₄ and SnCl₂ as raw material and photocatalytic activity of nano-scaled core-shell Sn²⁺-doped titania photocatalyst was studied in this paper. The as-prepared samples were studied by UV-Vis, XRD, XPS, TEM. The particles of Sn²⁺-doped TiO₂ photocatalyst, calcined from 150 to 600℃ for 5 h, possesses narrow particle size distribution and the sample was composed of anatase phase. Its photocatalytic efficiency was investigated by UV irradiation.
