| 摘 要： | 以钛酸四丁酯、正硅酸乙酯为前驱体，冰醋酸为水解抑制剂，用溶胶-凝胶法制备了纳米TiO2／SiO2复合粒子。考查了SiO2负载量、复合粒子焙烧温度、催化剂用量对活性艳红X-3B光催化降解率的影响。结果表明，当n（Ti）／n（Si）=3,焙烧温度为700℃、粒子添加量w（TiO2）／w（SiO2）=2％时对活性艳红X-3B降解性能最好。

| Abstract: | Nano TiO2/SiO2 was prepated by means of sol-gel using tetraethylorthosilicate and tetrabutylorthotitanate as precursors and glacial acetic acid as depressor.The effects ofthe photoeatalytic degradation of active brilliant red X-3B were researched through SiO2 loading,calcined temperature and photocatalyst dosage.Photocatalyst result showed that The TiO2/SiO2 of 3 Ti/Si mol ratio,calcined at 700℃ and 2% dosage had the best catalysis property. |
