大孔炭负载二氧化钛复合催化剂降解甲基橙性能研究

On photocatalytic degradation of TiO_2/C samples for methyl orange

制备了大孔炭负载二氧化钛光催化复合材料,在紫外光下降解甲基橙做其光催化性能评价。在相同条件下与P25光催化降解甲基橙相比较,TiO2/C的催化降解活性显著高于P25,并考察了复合催化剂的用量及循环使用次数。实验结果表明,TiO2/C复合材料光催化降解甲基橙是吸附与光催化降解的协同作用的结果,具有良好的催化降解活性。

TiO2/C composites have been prepared by a sol-gel method.The presenc e of macroporous carbon could act as an interesting template.Degradation of met hyl orange results indicated that the TiO2/C was enhanced the photocatalytic act ivity than P25.On the other hand it can be recycle used several times.
