Herein, an N, S-co-doped porous carbon electrocatalyst was fabricated using polyacrylonitrile (PAN), thiourea and diatomite as the precursors, sulfur source and hard template, respectively. The optimal catalyst (S-PAC-D) exhibits a high ORR performance, with a half-wave potential of 0.84 V (vs. RHE), as well as a predominant four-electron pathway, short-term stability and methanol resistance. After being constructed as a zinc\u2013air battery (ZAB), it can deliver a peak power density of 126.6 mW\u00b7cm\u22122 and a capacity of 804.1 mAh g\u22121Zn. This work offers a scalable, low-cost versatile methodology to fabricate high-performance non-noble metal ORR catalysts, which holds great promise for clean energy conversion devices.<\/jats:p>","DOI":"10.3390\/molecules31193526","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T10:02:27Z","timestamp":1791194547000},"page":"3526","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Diatomite-Templated Fabrication of Porous N, S-Co-Doped Carbon as High-Performance Catalyst for Oxygen Reduction"],"prefix":"10.3390","volume":"31","author":[{"given":"Qingqing","family":"Wang","sequence":"first","affiliation":[{"name":"School of Clinical Medicine, Hainan Vocational University of Science and Technology, Haikou 571126, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayi","family":"Su","sequence":"additional","affiliation":[{"name":"School of Clinical Medicine, Hainan Vocational University of Science and Technology, Haikou 571126, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3549-8908","authenticated-orcid":false,"given":"Haoxiong","family":"Nan","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenghang","family":"You","sequence":"additional","affiliation":[{"name":"Key Laboratory of Water Pollution Treatment and Resource Reuse of Hainan Province, School of Chemistry and Chemical Engineering, Hainan Normal University, Haikou 571158, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,10,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e08413","DOI":"10.1002\/adfm.202508413","article-title":"Highly Efficiency Seawater Electrolysis Guided by Coordinating Catalysis of Oxygen Evolution Reaction","volume":"36","author":"Yuan","year":"2026","journal-title":"Adv.
