摘要
以原位化学沉淀—光还原法制备了Ag-AgCl/石墨烯复合光催化材料。以罗丹明B为模型降解物,研究了其可见光催化性能。实验结果表明:石墨烯的引入使Ag-AgCl/石墨烯催化剂催化活性提高;当初始罗丹明B质量浓度为5 mg/L时,可见光照射60 min后罗丹明B的降解率可达99%;降解率随初始罗丹明B质量浓度的增加而减小。Ag-AgCl/石墨烯具有很高的可见光催化活性和稳定性。
The photocatalytic composite Ag-AgCl/ grapheme was prepared by in-situ chemical precipitation-photoreduction method and its visible-light photocatalytic activity was studied using Rhodamine B as degradation substrate. The experimental results show that: The catalytic activity of the catalyst is improved with the introduction of grapheme; When the initial mass concentration of Rhodamine B is 5 mg/L, its degradation rate can reach 99% after 60 min of visible-light irradiation; The degradation rate is decreased with the increasing of the initial mass concentration of Rhodamine B. The visible-light photocatalytic activity and stability of Ag-AgCl/grapheme are high.
