Advanced oxidation technology (AOPs) is an effective technology to treat water pollution, which has attracted recent attention. The non-selective and strong oxidation properties of hydroxyl radicals (·OH) in the AOPs reaction process are efficient enough to degrade pollutants. CuFeS2/g-C3N4 (CFS/CN) photofenton catalyst was synthesized by a simple hydrothermal/calcination method for degradation of Rhodamine B (RhB). The results show that CFS/CN 1∶2.5 has the optimum catalytic performance for RhB degradation at 0.10 g/L catalyst, 10 mg/L RhB concentration, 50 μL H2O2 addition and pH value 1. In addition, the degradation efficiency of CFS/CN for RhB is 90% at 15 min and nearly 96% at 20 min. According to the results of cyclic experiments, CFS/CN has a good cyclic stability. It is indicated that CFS/CN catalysts could provide a potential application for RhB degradation.

先进氧化技术(AOPs)是一种处理水体污染的新兴技术,近年来得到了广泛的关注。AOPs反应过程中羟基自由基(·OH)的非选择性和强氧化性能够高效降解污染物。通过简单的水热-煅烧法合成了CuFeS2/g-C3N4(CFS/CN)光Fenton催化剂并用于降解罗丹明B(RhB),通过研究催化条件对RhB降解效率的影响。结果表明:当催化剂用量为0.10 g/L、RhB质量浓度为10 mg/L、双氧水(H2O2)添加量为50 μL及pH值为1的条件下,CFS/CN 1∶2.5对RhB具有最佳的催化降解性能。此外,CFS/CN对RhB在15 min降解效率为90%,20 min接近96%。循环实验表明,CFS/CN具有良好的循环稳定性。因此,CFS/CN催化剂对RhB的降解提供了潜在的应用价值。

先进氧化技术(AOPs)是一种处理水体污染的新兴技术,近年来得到了广泛的关注。AOPs反应过程中羟基自由基(·OH)的非选择性和强氧化性能够高效降解污染物。通过简单的水热-煅烧法合成了CuFeS2/g-C3N4(CFS/CN)光Fenton催化剂并用于降解罗丹明B(RhB),通过研究催化条件对RhB降解效率的影响。结果表明:当催化剂用量为0.10 g/L、RhB质量浓度为10 mg/L、双氧水(H2O2)添加量为50 μL及pH值为1的条件下,CFS/CN 1∶2.5对RhB具有最佳的催化降解性能。此外,CFS/CN对RhB在15 min降解效率为90%,20 min接近96%。循环实验表明,CFS/CN具有良好的循环稳定性。因此,CFS/CN催化剂对RhB的降解提供了潜在的应用价值。

Advanced oxidation technology (AOPs) is an effective technology to treat water pollution, which has attracted recent attention. The non-selective and strong oxidation properties of hydroxyl radicals (·OH) in the AOPs reaction process are efficient enough to degrade pollutants. CuFeS2/g-C3N4 (CFS/CN) photofenton catalyst was synthesized by a simple hydrothermal/calcination method for degradation of Rhodamine B (RhB). The results show that CFS/CN 1∶2.5 has the optimum catalytic performance for RhB degradation at 0.10 g/L catalyst, 10 mg/L RhB concentration, 50 μL H2O2 addition and pH value 1. In addition, the degradation efficiency of CFS/CN for RhB is 90% at 15 min and nearly 96% at 20 min. According to the results of cyclic experiments, CFS/CN has a good cyclic stability. It is indicated that CFS/CN catalysts could provide a potential application for RhB degradation.
