摘要
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。
Rare earth doped TiO_2 coatings were prepared on the surface of tile by the solgel process, and the effects of rare earth oxide addition on the photocatalytic activities of TiO_2 were also investigated. Experimental results of photodecomposition Rhodamine B show that the addition of appropriate amount of rare earth oxide is effective for improving the photocatalytic activities of TiO_2.
