To address these challenges, this study engineers a ligand-stabilized permanganate/sulfite (Mn(VII)/S(IV)) system using nitrilotriacetic acid (NTA) for efficient degradation of recalcitrant organic pollutants across a wide pH range. The NTA coordination critically stabilizes reactive Mn intermediates (Mn(III) and Mn(V)), generated via two-electron reduction of Mn(VII) by S(IV), effectively mitigating their deactivation through hydrolysis or disproportionation at near-neutral pH. This stabilization enables sustained catalytic activity from pH 4–7.5, overcoming the strict acidic pH requirement of conventional Mn(VII)/S(IV) systems. Mechanistic investigations reveal dual oxidation pathways: Mn(III)–NTA species mediate radical-based oxidation through SO₄^•− generation, while Mn(V)−NTA species dominate non-radical two-electron oxidation process. Crucially, the Mn(VII)/S(IV) molar ratio serves as a tunable lever governing oxidation pathway selection: higher ratios favor non-radical Mn(V)−NTA oxidation, whereas lower ratios promote SO₄^•−-based pathways that are subject to self-quenching by excess S(IV). Dissolved oxygen further sustains the catalytic cycles by preventing premature Mn(V) reduction and facilitating oxysulfur radical chain propagation. Moreover, the NTA coordination confers exceptional resilience against common water matrix interferents (e.g., anions and natural organic maters), while maintaining high degradation efficacy in diverse natural waters. This work demonstrates that ligand-stabilized high-valent Mn(V) catalysis enables tunable and robust oxidation pathways, providing new mechanistic insights for precision oxidation technologies.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"713 ","pages":"Article 120811"},"PeriodicalIF":4.8,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of CeO₂ to the catalyst composition enhances its performance under reaction conditions. Another factor affecting the activity and thermal stability of such catalysts is the strength of the NiO-MgO interaction. In this research, the effects of calcination temperature on the textural characteristics, strength of NiO-MgO interaction, and catalytic performance of Ni-Mg-O and Ni-Ce-Mg-O in the dry reforming of methane are studied. As found, the sintering resistance of MgO is noticeably enhanced in the presence of CeO₂. Moreover, CeO₂ hinders the formation of Ni_xMg_1-xO solid solutions, thus improving the reducibility of Ni. The strength of the NiO-MgO interaction increased with the temperature for both the Ni-Mg-O and Ni-Ce-Mg-O samples, while the NiO-CeO₂ interaction was optimal after calcination at 600 °C. The increased stability of the CeO₂-containing catalyst under dry reforming conditions is due to the suppressed formation of carbon deposits. Among the Ce-containing catalysts, the samples calcined at 500 and 600 °С exhibited an optimal catalytic performance. Thus, the former demonstrated a higher conversion of the reagents, while the latter showed a higher stability. At a higher calcination temperature (700 °С), the weaker NiO-CeO₂ and NiO-MgO interactions worsened both the stability and catalytic activity. The Ni-Ce-Mg-O sample calcined at 600 °C was tested at 30 L/(g·h) and 750 °C for 140 h and demonstrated the values of CH₄ and CO₂ conversions of 89.6 and 90.2 %, respectively. As revealed by high-resolution transmission electron microscopy, regardless of calcination temperature, reduction of CeO₂ in hydrogen at 750 °C has led to the formation of highly dispersed clusters along with layers at the intra-crystallite boundaries. The interaction of these CeO₂ species with Ni is supposed to be responsible for the enhanced catalytic performance.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"713 ","pages":"Article 120801"},"PeriodicalIF":4.8,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These processes can be further advanced by debrominating BFRs into less harmful compounds with potential commercial value, thus supporting the principles of a circular economy. Herein, Ni/Al₂O₃ was employed for the catalytic debromination of tetrabromobisphenol A flame retardant in mixtures of H₂O, isopropanol and NaOH at modest reaction temperatures. Activity experiments conducted in an autoclave indicated that studied catalyst exhibits impressive debromination activity and complete selectivity towards C−Br bond scission. The catalyst reduction temperature was found to correlate with debromination activity, with higher temperatures yielding improved performance. Debromination proceeded under H₂ and also under N₂ in protic solvents via transfer hydrogenation. Catalyst characterization, coupled with high-resolution mass-spectrometry product analytics and deuterium labelling, suggested that the enhanced catalytic activity can be attributed to the activation of the metal-support interface and subsequent interactions with adsorbed solvent molecules and associated dissociation products on the alumina support. Used experimental conditions also provided high tolerance against bromine poisoning of the catalyst, in contrast to reference debromination experiments conducted in toluene. The study demonstrates the capability of Ni/Al₂O₃ as an efficient and affordable debromination catalyst in solvents of low environmental impact.
