【Abstract】 Rare earth doped TiO₂ 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 TiO₂ 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 TiO₂.更多还原
