To reduce silver consumption, we developed a novel Pb-Ag@γ-MnO₂ composite anode through a two-step strategy: (1) in-situ synthesis of Ag nanoparticle-decorated γ-MnO₂ (Ag@γ-MnO₂) via sequential MnO₄⁻/Mn<sup>2+</sup> redox reaction and Ag⁺ chemical reduction, followed by (2) uniform dispersion of 2.0 wt.% Ag@γ-MnO₂ particles in a Pb matrix using powder metallurgy. Systematic comparisons with industrial PbAg(0.5 wt.%) alloy and Pb composites containing individual Ag or γ-MnO₂ dispersoids (2.0 wt.%) revealed superior performance of the Pb-Ag@γ-MnO₂ composite anode. During galvanostatic polarization at 50 mA·cm⁻² in 160 g·L⁻¹ H₂SO₄, the Pb-Ag@γ-MnO₂ anode exhibited a 40 mV lower stable potential (1.33 V) than the PbAg(0.5 wt.%) benchmark. Electrochemical impedance spectroscopy and DFT calcultion confirmed its faster oxygen evolution reaction (OER) kinetics, evidenced by a lowest charge transfer resistance of 1.73 Ω·cm², linked to optimized adsorption/desorption of oxygen intermediates due to Ag nanoparticles decoration. Microstructural analysis revealed that Pb-Ag@γ-MnO₂ has a remarkably thinner (∼2.5 μm) and denser oxide layer compared to the porous 15–25 μm layer on PbAg alloys. Notably, with <0.08 wt.% total Ag content, an 84% reduction from conventional PbAg alloy anodes, the Pb-Ag@γ-MnO₂ achieved comparable performance to industrial counterparts. These findings establish Ag@γ-MnO₂ as dual-functional active sites that synergistically enhance OER activity while dramatically decreasing precious metal consumption.</div></div>","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"524 ","pages":"Article 146078"},"PeriodicalIF":5.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The corrosion resistance and discharge performance of Mg-xGd (<em>x</em> = 0, 1, 3, 8, 15, 20 wt.%) alloys as anodes for magnesium-air batteries are systematically investigated. Gd exists in Mg alloys mainly in the form of the Mg<sub>5</sub>Gd phase. The Mg<sub>5</sub>Gd phase acts as the cathodic phase to promote the dissolution of magnesium substrate during corrosion and discharge processes. A higher content of Gd is not favorable to the improvement of corrosion resistance and discharge properties.

This work presents molecular dynamics simulations of the catalyst-ionomer interface for an expanded Pt/C-ionomer thin film model. Simulations reveal that the structure of the ionomer film is sensitive to the oxidation state of the carbon support, with the preferential ionomer orientation shifting from backbone-towards-carbon to sidechain-towards-carbon oxide. The equivalent weight of the ionomer is shown to determine ionomer packing at the catalyst surface, which could impact the local oxygen transport resistance. The equivalent weight also influences the local proton concentration (or pH) and the proton conductivity at the catalyst-ionomer interface. Shorter sidechain length also increases conductivity by forming larger water clusters that act as channels for hydronium mobility. Overall, the presented simulations demonstrate how the ionomer composition could be tuned to enhance performance via its impact on kinetic, ohmic, and transport losses in fuel cell voltage.</div></div>","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"524 ","pages":"Article 146076"},"PeriodicalIF":5.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
