摘要
采用溶胶-凝胶法制备了La3+/TiO2光催化剂,在模拟太阳光照射下,考察了该催化剂对酸性红B的光催化降解效果。结果表明:掺杂量ω(La3+)1%、催化剂用量1g/L、通气量100mL/min、体系pH值是7时,50mg/L的酸性红B经3 h光催化降解,其降解率可达92.9%。与纯TiO2相比,La3+/TiO2光催化剂显示出良好的太阳光催化活性。
La3+/TiO3 photocatalyst is prepared by the sol-gel method. The photocatalytic degradation of Acid Red B under artificial sunlight irradiation is investigated. The results shows that the La3+ doped TiO2 exhibits greater photocatalytic activity than pure TiO2.
