Synergetic effect of photocatalysis and peroxymonosulfate activated by MFe₂O₄ (M = Co, Mn, or Zn) for enhanced photocatalytic activity under visible light irradiation

Abstract

The combined activation effects of photogenerated e−/h+, Fe, Co, Mn, and Zn on peroxymonosulfate to produce SO4˙− clearly enhanced the degradation efficiency.

Peroxymonosulfate enhanced photoelectrocatalytic degradation of 17α-ethinyl estradiol

“…The fact that the oxidant acts as a photoelectron trap contributes to the lower electron availability that end up at the cathode and the produced photocurrent decrease; on the contrary, the number of photoproduced holes that are available for EE2 oxidation increases due to the weakening of the e-/h+ recombination rate.
