PS/GR/g-C3N4光催化剂高效光催化系统的设计与性能评估

Design and Performance Evaluation of PS/GR/g-CN Photocatalyst High-Efficiency Photocatalytic System

采用聚苯乙烯(PS)微球模板法制备了高效聚苯乙烯/石墨烯/碳三氮四(PS/GR/g-C3N4)光催化剂,研究了在模拟太阳光照条件下对抗生素和染料的降解效率,同时比较了PS微球对GR/g-C3N4复合材料催化性能的影响。催化结果表明:PS/GR/g-C3N4光催化剂对于甲基橙和四环素都具有较高的降解效率,120 min后降解效率分别为99%和70.55%。循环性能分析结果表明,PS/GR/g-C3N4光催化剂在经过多次循环后仍然保持了良好的催化效率。

PS/GR/g-C3N4 photocatalyst was prepared by polystyrene(PS)microsphere template method,and the degradation efficiency of antibiotics and dyes was studied under simulated solar light conditions.The effect of PS microspheres on the catalytic performance of GR/g-C3N4 composites was compared.The results showed that PS/GR/g-C3N4 photocatalyst had high degradation efficiency for MO and tetracycline,and the degradation efficiency was 99%and 70.55%in 120 min.The cycling performance test showed that PS/GR/g-C3N4 photocatalyst maintained good catalytic efficiency after multiple cycles.
