TiO_2/GO纳米复合材料对制药废水的光催化处理

Photocatalytic Degradation of Pharmaceutical Wastewater by TiO_2/GO

本实验采用水热法制备了石墨烯(GO)负载纳米TiO_2材料,对负载前后的纳米材料降解制药废水的催化活性进行测定,并用SEM、FTIR和UV-vis对其晶体结构进行表征。由实验结果分析可得,石墨烯的成功负载对纳米TiO_2粉体的催化效率有显著影响,TiO_2/GO复合物对制药废水的色度降解在30min时可以达到95%以上,180min时COD去除率可达78%。

In this experiment, graphene （GO） and nano - TiO2 composites were prepared using hydrothennal method, the prepared powder was used for photocatalytic degradation and analytical methods, such as SEM, FTIR and UV - vis, were utilized in this study for characterization of the prepared powder. The experimental results show that, loading on graphene has a significant effect on the catalytic efficiency of TiO2, the degradation of pharmaceutical wastewater can reach above 95% when at 30rains and the degradation of COD can reach 78% when 180mins.
