【摘要】采用溶胶—凝胶浸渍提拉法制备ITO玻璃负载纳米TiO2 薄膜 ,再以蒽醌修饰 ,在紫外光照下用以处理孔雀石绿染料溶液。结果表明 ,蒽醌修饰TiO2 对降解产生了明显的改进。控制溶液pH值和H2 O2 的用量 ,降解率将进一步提高。更多还原

【Abstract】 The nanocrystalline TiO 2 films loaded on ITO grass were prepared by a sol-gel progress,and modified with anthraquinone.This modified electrode was used in the decoloration of malachite green under the UV lights.The result shows that anthraquione enhances the photocatalytic activity of TiO 2;furthermore,by controlling the pH and the use of H 2O 2,the photocatalytic activity can be improved.更多还原
