采用溶胶凝胶法在釉面砖上制备了均匀的 Ti O2 光催化薄膜 ,并研究了稀土元素铈、镧、钇掺杂对 Ti O2 光催化性能的影响。对罗丹明 B的光降解实验表明 :适量的稀土元素掺杂均可显著改善 Ti O2 薄膜的光催化性能。
The uniform Ti O2 photocatalytic films were prepared on the glazed tiles by sol-gel method. The effects of rare earth elements cerium, lanthanum and yttrium doping on the photocatalytic activity of Ti O2 were also studied. The photodegradation experiments of rhodamine B showed that the proper amount of rare earth elements doping could significantly improve the photocatalytic activity of Ti O2 thin films.
