摘要
纳米TiO2 采用掺杂过渡金属离子和固定化技术 ,能有效提高其光催化活性和反应效率 ,在处理废水有机污染物等方面具有广阔的应用前景。文章介绍了纳米TiO2 的光催化氧化降解机理、掺杂不同过渡金属离子对TiO2 光催化性能的影响和在不同基质上光催化活性的比较以及在制浆造纸废水处理等方面的研究进展。
The photocatalysis activity and reaction efficiency of titanium dioxide can be enhanced obviously by doping methods and fixation and it will has a promising future in the treatment of organic pollutant of wastewater. The mechanism of photocatalysis degradation with TiO_2 nanoparticles, the influence of doping various transition metal ions on the photocatalysis performance of TiO_2, comparison of the photocatalysis activity on different base materials are discussed.Finally the research progress on photocatalysis oxidation treatment of pulp and paper effluent with transition metal-doped TiO_2 nanoparticles is reviewed.
