摘要:
开发高效活化过一硫酸氢钾(PMS)的环保催化剂是环境催化领域一个崭新而极具挑战性的研究课题。本文采用水热法制备具有催化和磁性分离双重特性的纳米粒子CoFe-2O-4。通过XRD、XPS、VSM等对其进行表征,以染料亚甲基蓝(MB)为探针化合物,以PMS为氧化剂,考察CoFe-2O-4的催化性能。结果表明,10 min内CoFe-2O-4对MB的去除率高达98%,并且经磁性分离重复使用6次以后,其催化活性基本不变,表明CoFe-2O-4具有良好的重复使用性,而且CoFe-2O-4还能够催化降解酸性橙7、弱酸性桃红、活性艳橙、碱性绿1和活性艳红等多种染料。采用抗坏血酸为自由基捕获剂,结合电子顺磁共振波谱证实了CoFe-2O-4/PMS催化体系的氧化活性种主要为SO ·- 4与·OH,并推测了其催化反应机理。
