As the biochar increased the pH, however, the FeS–biochar composite was not as effective as FeS alone at removing DNT, indicating that an acidic medium may be necessary for the reductive removal of DNT by the FeS–biochar composite. In contrast, MnS and MnS–biochar composite were not as effective at reducing DNT as FeS and the FeS–biochar composite. FeS–biochar composites demonstrated good catalytic efficacy and enhanced persulfate- and H₂O₂-mediated DNT oxidation. The 50 wt% FeS–biochar composite (5 g dosage) removed 93% and 100% of DNT in the presence of persulfate/H₂O₂ (3 mmol L⁻¹), respectively, under the given conditions. Both the Fe²⁺ in the FeS and the carbon in the FeS–biochar composites contributed to the catalytic enhancement of the DNT oxidation. Radical quenching tests and electron paramagnetic resonance spectroscopic analysis revealed that sulfate (SO₄⁻∙) and hydroxyl (OH∙) radicals are dominant radical species to account for the enhancement of DNT oxidation.

The mechanism of water splitting on the nano-BeO surface was developed. Finally, the reported methods are useful for hydrogen production on a large scale. © 2025 Society of Chemical Industry (SCI).</p>\u0000 </section>\u0000 </div>","PeriodicalId":15335,"journal":{"name":"Journal of chemical technology and biotechnology","volume":"100 7","pages":"1463-1471"},"PeriodicalIF":2.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
