Abstract Singlet oxygen ( 1 O 2 ) has attracted great attention owing to its superior comprehensive oxidizing performance and extensive application in dealing with ever‐growing environmental pollution. However, the efficient catalytic generation of is very challenging due low activity most catalysts oxygen‐containing radicals reaction. Herein, C‐doped Co nanoparticles (CoNPs) supported on porous carbon (C─Co/C) as highly reactive selective ‐producing are demonstrated for oxidation recalcitrant organics via activation peroxymonosulfate (PMS). The doped C 2p orbitals can accept 3d electrons, thereby weakening Co─O bonding between PMS or other intermediates such *SO 4 , *OH, *OOH, *O. adsorption cleavage energy nanoparticle reduced from 8.09 4.64 eV by doping. barrier *OOH step also lowered significantly, kinetically improving .

O‐Bridged Co‐Cu Dual‐Atom Catalyst Synergistically Triggers Interfacial Proton‐Coupled Electron Transfer: A New Approach to Sustainable Decontamination

Abstract Heteroatom‐bridged dual‐atom catalysts (DACs), featuring more flexible active sites and intermetallic interaction, provide an opportunity for sustainable environmental remediation. Herein, innovative oxygen‐bridged Co‐Cu DAC supported on nano‐alumina (CoOCu‐DAC) is fabricated using a straightforward two‐step process. The as‐prepared catalyst significantly enhances both decontamination kinetics peroxymonosulfate (PMS) utilization efficiency by 1–3 orders of magnitude toward monoethanolamine (MEA, p K = 9.5) compared to Co single‐atom (Co‐SAC) bulk metal catalysts, largely outperforms previously reported systems. In‐situ ATR‐FTIR theoretical investigations reveal that the secondary introduction Cu plays multiple important roles: it activates lattice oxygen trigger key proton transfer (PT) MEAH + via nucleophilic attack at interface subsequently favors deprotonated MEA as efficient electron donor accelerate (ET) enhancing orbital overlaps co‐activation O 2 PMS. Such stepwise proton‐coupled (PCET)‐enhanced catalytic pathway mediated CoOCu‐DAC fundamentally different from common route identified in Co‐SAC‐involved Fenton‐like system. established binary QSAR further substantiates universality PCET‐enhanced strategy versatile nitrogen‐containing organic compounds. This study offers new perspective water other related areas catalysis based rationalized design multifunctional atomic level.
