Title
Visible light photocatalytic activities of S-doped TiO2-Fe3+ in aqueous and gas phase
Abstract

The photocatalytic activity of a sulfur-doped titanium dioxide material with adsorbed ferric oxide was analyzed for the degradation of different model compounds. Dichloroacetic acid (DCA) was decomposed in the aqueous phase and NOx was decomposed in the gas phase. The stability of the photocatalyst was examined as a function of the recycling times by degradation of DCA at pH 3. The photocatalyst showed quite high photoactivity under visible light illumination. The best performance for decomposing DCA was obtained at pH 3. Results of inductively coupled sequential plasma (ICPS) analysis indicated that this photocatalyst is stable and appropriate for long-term commercial applications.
