Improved adsorption and degradation performance by S-doping of (001)-TiO.

In this work, sulfur-doped (S-doped) TiO with the (001) face exposed was synthesized by thermal chemical vapor deposition at 180 or 250 °C using S/Ti molar ratios of 0, 0.5, 1, 2, 3, 4 and 5. The S-doped samples synthesized at 250 °C exhibit a significantly improved photocatalytic performance.
