Currently, anode materials for alkaline anion-exchange membrane fuel cells still rely on platinum-based catalysts, posing a challenge to the development of efficient low-Pt or Pt-free catalysts. Low-cost ruthenium-based anodes are being considered as alternatives to platinum. However, they still suffer from stability issues and strong oxophilicity. Here, we employ a metal\u2013organic framework compound as a template to construct three-dimensional porous ruthenium\u2013tungsten\u2013zinc nanocages via solvothermal and high-temperature pyrolysis methods. The experimental results demonstrate that this porous ruthenium\u2013tungsten\u2013zinc nanocage with an electrochemical surface area of 116 m2 g\u22121 exhibits excellent catalytic activity for hydrogen oxidation reaction in alkali, with a kinetic density 1.82 times and a mass activity 8.18 times higher than that of commercial Pt\/C, and a good catalytic stability, showing no obvious degradation of the current density after continuous operation for 10,000 s. These findings suggest that the developed catalyst holds promise for use in alkaline anion-exchange membrane fuel cells.<\/jats:p>","DOI":"10.3390\/nano14090808","type":"journal-article","created":{"date-parts":[[2024,5,6]],"date-time":"2024-05-06T15:09:36Z","timestamp":1715008176000},"page":"808","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Porous Ruthenium\u2013Tungsten\u2013Zinc Nanocages for Efficient Electrocatalytic Hydrogen Oxidation Reaction in Alkali"],"prefix":"10.3390","volume":"14","author":[{"given":"Xiandi","family":"Sun","sequence":"first","affiliation":[{"name":"Anhui Province Key Laboratory of Value-Added Catalytic Conversion and Reaction Engineering, Anhui Province Engineering Research Center of Flexible and Intelligent Materials, School of Chemistry and Chemical Engineering, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyuan","family":"Cheng","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Value-Added Catalytic Conversion and Reaction Engineering, Anhui Province Engineering Research Center of Flexible and Intelligent Materials, School of Chemistry and Chemical Engineering, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hang","family":"Liu","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Value-Added Catalytic Conversion and Reaction Engineering, Anhui Province Engineering Research Center of Flexible and Intelligent Materials, School of Chemistry and Chemical Engineering, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siyu","family":"Chen","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Value-Added Catalytic Conversion and Reaction Engineering, Anhui Province Engineering Research Center of Flexible and Intelligent Materials, School of Chemistry and Chemical Engineering, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ya-Rong","family":"Zheng","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Value-Added Catalytic Conversion and Reaction Engineering, Anhui Province Engineering Research Center of Flexible and Intelligent Materials, School of Chemistry and Chemical Engineering, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4511","DOI":"10.1039\/D2EE02216H","article-title":"Toward the fast and durable alkaline hydrogen oxidation reaction on ruthenium","volume":"15","author":"Zhang","year":"2022","journal-title":"Energy Environ.
