Here, we used enzymolytic lignin (EL), melamine, and thiourea as carbon, nitrogen, and sulfur sources and NH4Cl as an activator to prepare N- and S-codoped lignin-based polyporous carbon (ELC) by one-step pyrolysis. The prepared lignin-derived biocarbon material (ELC-1-900) possessed a high specific surface area (844 m2 g\u22121), abundant mesoporous structure, and a large pore volume (0.587 cm3 g\u22121). The XPS results showed that ELC-1-900 was successfully doped with N and S. ELC-1-900 exhibited extremely high activity and stability in alkaline media for the ORR, with a half-wave potential (E1\/2 = 0.88 V) and starting potential (Eonset = 0.98 V) superior to those of Pt\/C catalysts and most non-noble-metal catalysts reported in recent studies. In addition, ELC-1-900 showed better ORR stability and methanol tolerance in alkaline media than commercial Pt\/C catalysts.<\/jats:p>","DOI":"10.3390\/ma16247614","type":"journal-article","created":{"date-parts":[[2023,12,12]],"date-time":"2023-12-12T09:15:33Z","timestamp":1702372533000},"page":"7614","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Enzymolytic Lignin-Derived N-S Codoped Porous Carbon Nanocomposites as Electrocatalysts for Oxygen Reduction Reactions"],"prefix":"10.3390","volume":"16","author":[{"given":"Zheng","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xia","family":"Qu","sequence":"additional","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuwei","family":"Feng","sequence":"additional","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lili","family":"Dong","sequence":"additional","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"},{"name":"Changzhou Key Laboratory of Biomass Green, Safe & High Value Utilization Technology, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yantao","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"},{"name":"Changzhou Key Laboratory of Biomass Green, Safe & High Value Utilization Technology, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tingzhou","family":"Lei","sequence":"additional","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"},{"name":"Changzhou Key Laboratory of Biomass Green, Safe & High Value Utilization Technology, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suxia","family":"Ren","sequence":"additional","affiliation":[{"name":"Institute of Urban & Rural Mining, Changzhou University, Changzhou 213164, China"},{"name":"Changzhou Key Laboratory of Biomass Green, Safe & High Value Utilization Technology, Changzhou 213164, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1703691","DOI":"10.1002\/adma.201703691","article-title":"Advanced Biomass-Derived Electrocatalysts for the Oxygen Reduction Reaction","volume":"30","author":"Borghei","year":"2018","journal-title":"Adv.
