| Abstract: The sulfur-doped titanium dioxide (S/TiO2) was prepared by calcinations. The photocatalytic decomposition of benzoic acid solution was carried out under simulated sun light; the photocatalytic activity is 2.7 times of TiO2. The results of XRD show that the sulfur can restrain the crystallization transformation of TiO2 from anatase to rutile, although the calcinations temperature has attained 500 ℃, the crystallization still is anatase entirely. The responsive wavelength range of S/TiO2 was shifted; it has obvious absorption in the region from 320 to 550 nm. The S (S6+) substituted for some of the lattice titanium atoms in S/TiO2. At the same time the XRF also prove the formation of S6+ and the atomic content is 2.13%. |
