Abstract A series of novel N-doped TiO2/graphene aerogel (NTGA) composites were successfully prepared by a chemical reduction self-assembly method. The NTGA composites were characterized by XRD, XPS, SEM and TEM, and their photo-generated electron transfer performance was measured by EIS. All NTGA composites exhibit excellent adsorption property and visible light photocatalytic ability, and the removal rates of Methlyene blue (MB) (20 ppm, 100 ml) reach to more than 90%. In sum, this strategy provides a new thought to enhance the adsorption and photocatalytic performance of N-doped TiO2 (NT).

三维网络石墨烯气凝胶增强氮掺杂二氧化钛的吸附和可见光光催化

摘要 采用化学还原自组装方法成功制备了一系列新型N掺杂TiO2/石墨烯气凝胶（NTGA）复合材料。通过XRD、XPS、SEM和TEM对NTGA复合材料进行表征，并通过EIS测量其光生电子转移性能。所有NTGA复合材料均表现出优异的吸附性能和可见光光催化能力，对亚甲蓝（MB）（20 ppm，100 ml）的去除率达到90%以上。总之，该策略为增强N掺杂TiO2（NT）的吸附和光催化性能提供了新思路。
