The biggest problem with Fe/PMS (peroxymonosulfate) system is the slow generation rate of SO4− due to inefficient Fe3+/Fe2+ cycle and the low decomposition efficiency of PMS. Here, we report the Fe3+-enhanced decomposition of PMS by a two-dimensional transition metal dichalcogenide WS2 for pollutant...
