  • 摘要: 通过溶胶-凝胶法制备了同时具有可见光(Vis)光催化和Fenton催化双重活性的Co-TiO2催化剂。通过对比Vis/Co-TiO2/KHSO5、Co-TiO2/KHSO5和Vis/Co-TiO2 3种体系对苯酚的降解效果,Vis/Co-TiO2/KHSO5表现出明显的Fenton-光催化协同作用。进一步研究pH值、KHSO5与苯酚摩尔比(nKHSO5:nC6H6O)和Co-TiO2投加量(mCo-TiO2)对Fenton-光催化协同降解苯酚效果的影响。结果表明,pH=6.9、nKHSO5:nC6H6O=10:1、mCo-TiO2=1.0 g/L时,降解率达100%。最后,结合XRD、XPS和UV-DRS等手段和催化活性实验数据分析了Vis/Co-TiO2/KHSO5体系的催化机理。
