摘要
文章采用一种简单的方法于低温条件下制备出掺铁纳米TiO2溶胶。通过在可见光条件下对吖啶橙的光催化降解,对掺铁纳米TiO2溶胶和纳米TiO2溶胶的光催化活性进行了研究比较,结果表明掺铁纳米TiO2溶胶的光催化活性较高,铁的掺杂量为1%时光降解效果较好。
Fe-doped TiO2 hydrosol was prepared by hydrolyzation of tetrabutyl titanate followed by acidic peptization of the precipitate under 70℃.The method was highly simplified.The influence of iron doption to photocatalytic decomposability of dioxide titanium for organic contamination by using acridine orange as target decomposition material under visible light irradiation was investigated.Results showed that the photocatalytic decomposability of TiO2 doped with iron was higher than pure TiO2,with optimism concentration of 1% Fe.
