ealloying of Al70Pd17Fe13 quasicrystal alloy and the electrocatalytic performance study of nanoporous palladium
本文研究了快淬Al70Pd17Fe13二十面体准晶合金在0.1M NaCl水溶液中的电化学脱合金化行为。在脱合金化初期，准晶晶粒分解成纳米晶，纳米晶继续脱合金化生成纳米多孔Pd结构。 纳米多孔Pd的孔径约为10 nm，韧带厚度约为5 nm。该纳米多孔Pd在碱性环境中对乙醇电氧化显示出高的催化活性和稳定性。
he electrochemically dealloying behaviour of a rapidly quenched icosahedron Al70Pd17Fe13 quasicrystal alloy in 0.1 M NaCl aqueous solution has been studied. Upon dealloying, the quasicrystal grain first decomposed into nanocrystals and then nanocrystals turned into a nanoporous palladium structure. The resultant nanoporous Pd has a pore size of ~ 10 nm and a ligament thickness of ~ 5 nm. The nanoporous Pd exhibits remarkable electrocatalytic activity and stability towards the oxidation of ethanol in alkaline environment.
