Abstract

Abstract:

A sol-gel method was used to prepare TiO₂ and sulfur-TiO₂(S-TiO₂) nanocomposites, which were characterized by N₂ adsorption-desorption, X-ray diffraction, X-ray photoelectron spectroscopy, photoluminescene, ultraviolet visible and transmission electron microscopy measurements. The photocatalytic performance of TiO₂ and S-TiO₂ nanocomposites, with respect to the photocatalytic oxidation of cyanide under visible light irradiation, was determined. The results reveal that S is well dispersed on the surface of TiO₂ nanoparticles. Additionally, the surface area of the S-TiO₂ nanocomposites was observed to be smaller than that of the TiO₂ nanoparticles because of blocked pores caused by doping with S. The S-TiO₂ nanocomposite (0.3 wt% S) exhibited the lowest band gap and the highest photocatalytic activity in the oxidation of cyanide. The photocatalytic performance of S-TiO₂ (0.3 wt% S) nanocomposites was stable, even after the fifth reuse of the nanoparticles for the oxidation of cyanide.

Key words: Titanium dioxide, Sulfur-doping, Photocatalyst, Cyanide oxidation
