摘要：

This work focused on the mechanism of photogenerated hole (h+) mediating the generation of active species in visible-light-assisted photocatalytic peroxymonosulfate (PMS) activation. Ferrous gluconate derived iron-doped carbon dots (Fe-CDs) were synthesized to investigate the vital role of h+ in the process of photocatalytic PMS activation for acetaminophen degradation by quenching experiments, ESR spectra, and DFT calculations. Within 20 minutes, Fe-CDs/PMS/Vis system can achieve a 100 % degradation of acetaminophen (15 μM) with low-additi...
