Abstract In this study, Co-doped manganese oxide octahedral molecular sieve (Co-OMS-2) has been successfully synthesized. The Co-OMS-2 catalyst shows high efficiency and excellent stability in activating peroxymonosulfate (PMS) to generate sulfate radicals for the degradation of Reactive Blue 19 in aqueous solution. The results illuminate the degradation efficiency has been enhanced by increasing catalyst dose and PMS concentration. Moreover, Co-OMS-2 has been successfully reused 5 times without significant decrease in the catalytic activity by the simple filtration.

用于降解水溶液中活性蓝 19 的高效 Co-OMS-2 催化剂

摘要 本研究成功合成了Co掺杂的氧化锰八面体分子筛(Co-OMS-2)。Co-OMS-2 催化剂在活化过一硫酸盐 (PMS) 以生成硫酸根以降解水溶液中的活性蓝 19 方面显示出高效和出色的稳定性。结果表明，通过增加催化剂剂量和 PMS 浓度提高了降解效率。此外，通过简单的过滤，Co-OMS-2 已成功重复使用 5 次，催化活性没有显着降低。
