负载于刻蚀镍泡沫上钯纳米粒子作为乙醇氧化高性能电催化剂
Pd Nanoparticles Supported on the Etched Ni Foams as High-Performance Electrocatalysts for Direct Ethanol Fuel Cells
摘要
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.关键词
