研究了一种吸附氧化铁的掺硫二氧化钛材料对不同模型化合物的光催化活性。二氯乙酸（DCA）在水相分解，nox在气相分解。通过pH值为3的DCA降解，考察了光催化剂的稳定性与循环次数的关系。该光催化剂在可见光照射下表现出较高的光活性。pH为3时，DCA的分解效果最佳。电感耦合序列等离子体（ICPS）分析结果表明，该光催化剂性能稳定，适合长期商业应用。
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 NOxwas 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.
