Abstract Fenton processes allow to degrade and mineralize toxic organic contaminants, yet classical require continuously adding hydrogen peroxide ferrous ions, costly solution pH adjustment, treatment of secondary iron sludge pollution. Heterogeneous electro-Fenton deliver oxidizing radicals with only oxygen electricity consumed. Bifunctional catalysts the synthesis activation simultaneously, eliminate additional chemical reagents, yield no metal residues in treated water. Here, we review bifunctional for heterogeneous processes. We describe mechanisms radical generation from oxygen. Then, compare different types based on their elemental compositions: (1) metal/carbon composite catalysts, i.e., monometallic iron/carbon bimetallic/trimetallic carbon transition single-atom catalysts; (2) without carbon; (3) metal-free catalysts. present five other approaches beyond electrocatalysts, which have been used improve performance

The presence of selenium vacancies (VSe) in metal selenides enables the activation peroxymonosulfate (PMS) for efficient water purification. However, mechanisms interactions VSe with PMS and organic pollutant removal are unclear. Hence, we precisely prepared a series FeSe2@MoO3 composites effective various pollutants. roles explored via density functional theory (DFT) calculations: (i) regulating electron distribution Fe Mo orbitals enhancing adsorption (ii) promoting conversion transition metallic redox pairs (Fe3+/Fe2+ Mo6+/Mo5+/Mo4+). as-prepared FeSe2@MoO3-8 exhibits excellent catalytic performance which nearly 100% efficiencies pollutants achieved within 2–10 min. quenching experiments, electronic spin resonance (ESR), probe tests demonstrated that multiple reactive species like SO4•–, O2•–, •OH, 1O2 contributed to 2,4-D. Finally, was attached polyvinylidene difluoride (PVDF) membrane continuous 2,4-D, efficiency total carbon 2,4-D were > 90% >70% 12 h operation.
