Herein, we report a hydrothermally synthesized metal chalcogenide cluster-based framework (NCF-3-Mn), which is decorated with transition metal complexes ([Mn(TEPA)]2+, TEPA = tetraethylenepentamine), for an electrocatalytic O2 reduction reaction (ORR). Benefitting from the abundant Mn-S bonds and Mn-N-C structures in NCF-3-Mn, it was found that NCF-3-Mn displayed a high onset potential (0.90 V) and an efficient four-electron transfer reaction pathway, which are much better than those of its analogue framework (T2-GaSbS). Moreover, NCF-3-Mn also exhibited a considerable long-term stability and methanol resistance toward ORRs. This work will present new opportunities for exploring the utilization of chalcogenide frameworks as novel non-Pt electrocatalysts for ORRs.<\/jats:p>","DOI":"10.3390\/nano15151186","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T09:41:17Z","timestamp":1754300477000},"page":"1186","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Stable Metal Chalcogenide Cluster-Based Framework Decorated with Transition Metal Complexes for an Efficient Electrocatalytic O2 Reduction Reaction"],"prefix":"10.3390","volume":"15","author":[{"given":"Xiang","family":"Wang","sequence":"first","affiliation":[{"name":"College of New Energy Materials and Chemistry, Leshan Normal University, Leshan 614000, China"},{"name":"Leshan West Silicon Materials Photovoltaic and New Energy Industry Technology Research Institute, Leshan 614000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Chemistry, Chemical Engineering and Materials Science, Soochow University, Suzhou 215123, China"},{"name":"Hongguang Middle School, Nanjing 210018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Wu","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Functional Supramolecular Coordination Materials and Applications, College of Chemistry and Materials Science, Jinan University, Guangzhou 510632, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11188","DOI":"10.1039\/D4SC02853H","article-title":"Selective oxygen reduction reaction: Mechanism understanding, catalyst design and practical application","volume":"15","author":"Li","year":"2024","journal-title":"Chem.
