磁性氧化石墨烯/TiO2复合材料的制备及光催化降解染料废水的研究

摘要

In order to improve the photoeatalytie performanee of TiO2 ,this experiment use graphite oxide made from Hummers method,nano-sized TiO2 ,FeCl3 to synthetize a speeial photoeatalytie nanoeomposite whieh named magnetie GO/TiO2 . This artiele studies the photoeatalytie nanoeomposite in different ratio under UV irradiation by using X-3B simulated wastewater. The result show that the best photoeatalytie ae-tivity is 3% GO in TiO2/GO. The degradation rate ean reaeh 93% in 1. 4 h when GO in magnetie TiO2/GO is 8%.%为了提高TiO2的光催化性能，采用Hummers法自制氧化石墨、纳米TiO2、FeCl3等为原料制备了磁性氧化石墨烯/TiO2（磁性GO/TiO2）复合光催化材料。以活性艳红X-3B为模拟废水，对该催化剂在紫外光下的催化活性进行了评价。结果表明，TiO2/GO材料中GO含量为3%时光催化活性最好，磁性GO/TiO2复合材料GO 含量为8%时在1.4 h时可以达到93%的降解率。
