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.
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+H2 SO4+H3 PO4+CH3 COOH)(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.
