Nevertheless, fabricating such catalysts with low Pt loading via low-cost, solvent-free, and size-controllable synthetic protocols remains an open space to be explored. Herein, we combined an all-solid-state synthesis of ZIF-8 precursor with a direct confined pyrolysis for the uniform anchoring of PtFe alloy nanoparticles on nitrogen-doped carbon derived from ZIF-8 (PtFe\/NC). The resulting PtFe\/NC catalyst with only 1.59 wt % Pt exhibits a remarkable half-wave potential of 0.897 V and a mass activity of 2.34 A mgPt\u20131 (@0.90 V, iR-free), outperforming commercial 20 wt % Pt\/C (0.14 A mgPt\u20131) by a factor of 17. We have confirmed that Fe doping can effectively restrict the growth of Pt particles. Meanwhile, integrating Fe atoms into the Pt lattice results in a 3.6% lattice compression, which correspondingly downshifts the d-band center and optimizes the adsorption strength toward reaction intermediates, thereby facilitating oxygen release and significantly enhances the catalytic activity.<\/jats:p>","DOI":"10.1021\/acsami.6c07261","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T00:24:09Z","timestamp":1783988649000},"page":"39793-39801","source":"Crossref","is-referenced-by-count":0,"title":["All-Solid-State Confinement\nSynthesis of PtFe Alloy\nAnchored on N-Doped Carbon for Acidic Oxygen Reduction"],"prefix":"10.1021","volume":"18","author":[{"given":"Wengang","family":"Chen","sequence":"first","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haocong","family":"Cheng","sequence":"additional","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5463-6600","authenticated-orcid":true,"given":"Jiahui","family":"Lyu","sequence":"additional","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Gong","sequence":"additional","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5439-5421","authenticated-orcid":true,"given":"Cheng","family":"Chen","sequence":"additional","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]},{"name":"Sanya Science and Education Innovation Park of Wuhan University of Technology , ,","place":["Hainan, China, 572000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2106-9846","authenticated-orcid":true,"given":"Zhijun","family":"Jiang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Jiaotong University , , ,","place":["Xi\u2019an, China, 710049"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4253-613X","authenticated-orcid":true,"given":"Wei","family":"Sang","sequence":"additional","affiliation":[{"name":"National University of Singapore (Chongqing) Research Institute , ,","place":["Chongqing, China, 401123"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3902-0976","authenticated-orcid":true,"given":"Shichun","family":"Mu","sequence":"additional","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5377-2376","authenticated-orcid":true,"given":"Zongkui","family":"Kou","sequence":"additional","affiliation":[{"name":"Wuhan University of Technology , , ,","place":["Wuhan, China, 430070"]},{"name":"National University of Singapore (Chongqing) Research Institute , ,","place":["Chongqing, China, 401123"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,13]]},"reference":[{"issue":"4","key":"2026072908062739500_cit1","doi-asserted-by":"publisher","DOI":"10.1002\/cnl2.70023","article-title":"Aqueous Rechargeable Zn-Air Batteries for Sustainable Energy Storage","volume":"4","author":"Gupta","year":"2025","journal-title":"Carbon Neutralization"},{"issue":"17","key":"2026072908062739500_cit2","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.adn0947","article-title":"Electrochemical Oxidation of Concentrated\nBenzyl Alcohol to High-Purity Benzaldehyde via Superwetting Organic-Solid-Water\nInterfaces","volume":"10","author":"Shi","year":"2024","journal-title":"Sci.
