摘要/Abstract

摘要： 发展具有高催化活性和高稳定性的非Pt阳极催化剂目前仍面临着巨大的挑战. 除了设计催化剂以外，设计合适的载体对提高电催化剂性能也具有重要意义. 在这篇论文中，作者报导了一种以混合酸(HNO₃+H₂SO₄+H₃PO₄+CH₃COOH) 腐蚀的镍泡沫负载Pd纳米粒子作为高性能电催化剂用于碱性条件下乙醇氧化. 因具有开放孔结构、快速电解质渗透能力及快速的电荷传输性能，这些镍泡沫负载的Pd纳米粒子显示了很好的电催化活性和循环稳定性，显示了该材料在乙醇阳极氧化具有较好的应用前景.

Abstract: The development of non-Pt anode electrocatalysts with high activity and long-term durability at low cost for fuel cells still remains enormous challenge. Here we report the Pd nanoparticles supported on Ni foams etched by the mixed acids (HNO₃+H₂SO₄+H₃PO₄+CH₃COOH) (Pd/ME-NF) that are designed and fabricated as high-performance electrocatalysts for ethanol oxidation in alkaline media. Because of the advantages of large open space, fast electrolyte penetration/diffusion and rapid electron transfer process, the Pd/ME-NF catalysts exhibited significantly improved electrocatalytic activity and durability compared with the commercial Pd/C catalysts.

Key words: Pd nanoparticle, Ni foam, mixed acids etching, electrocatalyst, ethanol oxidation
