| 摘 要： | 以不同的含钛化合物作为原料,在无模板条件下经一步溶剂热法合成了两种TiO2介孔球——TiO2-1和TiO2-2。对两种TiO2介孔球的形貌进行了表征,结果表明:TiO2-1和TiO2-2粒径分别为5.7 nm和8.0 nm;比表面积分别为159.4 m2/g和128.3 m2/g;孔径约为4.0 nm和5.0 nm。采用P25型TiO2、TiO2-1和TiO2-2对双酚A溶液进行光催化降解反应。在催化剂加入量为0.5 mg/L的条件下降解60 min,双酚A去除率分别为76.3%,99.7%,98.5%。TiO2-1和TiO2-2的光催化效果优于P25型TiO2,且TiO2-1的光催化效果更好。 |

| Abstract: | Two kinds of TiO2 mesoporous spheres,TiO2-1 and TiO2-2,were synthetized by one-step solvent-thermal process without template using different titanium-containing compounds as raw materials.The two kinds of TiO2 mesoporous spheres were characterized.The results show that the sizes,specific surface areas,pore sizes of TiO2-1 and TiO2-2 are 5.7 nm and 8.0 nm,159.4 m2/g and 128.3 m2/g,4.0 nm and 5.0 nm respectively.The degradation reactions of bisphenol A by photocatalysis with P25-type TiO2,TiO2-1 and TiO2-2 were investigated.The results show that under the conditions of catalyst dosage 0.5 mg/L and degradation time 60 min,the bisphenol A removal rates are 76.3%,99.7%,98.5% respectively,which indicates that the photocatalytical effects of TiO2-1 and TiO2-2 are better than that of P25-type TiO2,and that of TiO2-1 is the best. |
