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 . C─Co/C promotes 100% high modified kinetic model K values 457.0 94.5 µmol s −1 g rhodamine (RhB) 2,4‐dichlorophenol (2,4‐DCP), respectively.

Biochar has been widely employed for the promotion of advanced oxidation processes (AOPs) and when combined with nitrogen doping charge distribution mediation, N-doped biochar (NBC) can serve as a highly effective catalyst degradation persistent organic pollutants. However, due to variety preparation methods, intrinsic active sites AOP catalysis have not clearly identified. Furthermore, complex relationships between method, material properties, catalytic pathways remain unclear, impeding widespread practical application NBC. Herein, machine learning (ML) was implemented predict pathway identify vital properties N-doping required acceleration AOPs. During process model training, an innovative method data set splitting applied, comparing results generated from multiple models enhance interpretability. We elucidated correlation primary features nonradical pathway, focusing on contribution N species regulatory role pyrolysis temperature. Detailed insights were further provided ratio design NBC mediation. Overall, this study offers novel into NBC-mediated AOPs pollution control, underscoring significant potential ML accelerating applications.
