Research summary
Persulfate-based advanced oxidation processes (AOPs) using carbon-based catalysts are the dominant theme. N-doped graphitic biochars (N-BCs) annealed above 700 °C gave highly graphitic nanosheets with large specific surface area; N-BC900 activated peroxydisulfate (PDS) for degradation of Orange G, phenol, sulfamethoxazole, and bisphenol A at rates 39× and 6.5× higher than appropriate references [4]. N-doped carbon nanotubes (NoCNTs) were used as metal-free catalysts for phenol oxidation with peroxymonosulfate (PMS), and a nonradical pathway accompanied by radical generation was characterized in detail to elucidate the role of nitrogen heteroatoms [6]. The distinct intrinsic roles of nitrogen in CNT-mediated PMS versus PDS activation were dissected, showing that N-doping enhances PMS adsorption and the redox potential of derived N-CNT-PMS* complexes [7]. A review in Accounts of Chemical Research outlined how core/shell graphitic carbon hybrids, structural defects, and N dopants can switch the persulfate/carbon system from radical to nonradical oxidation, with metal-nanoparticle encapsulation modulating electronic density via charge transfer [1]. Singlet oxygen was identified as the primary ROS in PDS activation by crystallographic manganese oxides at neutral pH, generated by direct oxidation or recombination of superoxide and radicals from a metastable Mn intermediate [2]. Electron-transfer regimes in PS-NOPs were reviewed in detail, covering catalyst design, in situ/operando characterization, and mechanistic insights into surface-activated persulfate complexes [3]. Single-atom catalysts (SACs), particularly carbon-based SACs, were reviewed as candidates for AOP-based environmental remediation, with metal centers, carbon matrices, and coordination characteristics jointly setting the electronic features that determine peroxide-activation behavior and AOP efficiency [5].
