Summary: The catalytic performance of single-atom Fe sites in PMS activation is successfully enhanced by molecular engineering on the polymeric carbon nitride (CN) framework. The regulation of polymerization process by benzene-1,4-diamine increases the carbon/nitrogen ratio and shifts the valence of single-atom Fe, resulting in favorable thermal dynamics for the high-valent Fe(IV)=O involved oxidation reaction. The carbon-rich CN supported single-atom Fe catalyst exhibits remarkable performance in the selective degradation of organic pollutants via the high-valent Fe(IV)=O oxidation pathway. These findings highlight the importance of electronic properties of the support as essential descriptors for robust single-atom catalysts in pollutant abatement.

Summary: Rational design of graphitic carbon nitride (g-C3N4) engineered hematite (Fe2O3)/reduced graphene oxide (rGO) photocatalysts has been successfully employed for visible-light-driven photo-Fenton-like degradation of sulfamethoxazole (SMX). The optimal photocatalyst showed exceptional performance due to the successful integration of g-C3N4/Fe2O3/rGO, enabling efficient separation and migration of photoinduced charge carriers (e/h+). The study also optimized the photochemical decomposition efficiency by analyzing important reaction parameters such as catalyst loading, H2O2 dosage, pH, and temperature, and proposed a possible mechanism for SMX degradation based on the generation of reactive species and degradation intermediates.

Summary: This study comprehensively analyzed the molecular transformation behavior of dissolved organic matters (DOM) during peroxymonosulfate (PMS) activation by biochar for organic degradation. Different types of reactions were observed, including oxidative decarbonization, dehydrogenation, dehydration, deheteroatomisation, hydration, and N/S oxidation reactions. Certain compounds present in DOM showed moderate or strong inhibition effects on contaminant degradation. This information can be used to regulate ROS composition and DOM conversion process in PMS systems and minimize the interference of DOM conversion intermediates on PMS activation and degradation of target pollutants.

Summary: Carbocatalyst/persulfate is a green, highly oxidative system for decontaminating refractory aqueous organic pollutants. The interfacial electric field (IEF) is used to alter the catalytic activity and selectivity of carbon/persulfate systems via the field-dipole effect. Positive IEF induces/reinforces the nonradical oxidation pathway, while different persulfate activation pathways can be induced under negative IEF. This work extends the application of the interfacial electric field in persulfate-based advanced oxidation processes.
