Synthesis of high-efficiency catalysts for alcohol oxidation reaction caused great interest in direct alcohol fuel cells (DAFCs). Ultrathin PdFePb nanowires (NWs) with an average diameter of 2.3 nm were synthesized by a simple and fast one-pot aqueous synthesis, using octylphenoxypolyethoxyethanol (NP-40) as the structure-directing agent. The as-prepared PdFePb NWs displayed an increscent electrochemically active surface area (ECSA, 121.18 m g ). For ethylene glycol oxidation reaction (EGOR) and glycerol oxidation reaction (GOR), PdFePb NWs exhibited much higher activity and superior stability, outperforming those of homemade PdFe NWs, PdPb NWs, commercial Pd black and Pd/C (20 wt%). These results reveal dramatically high catalytic activity and durability of ultrathin PdFePb NWs in enhancing polyols electrooxidation.
用于醇氧化反应的高效催化剂的合成在直接醇燃料电池（DAFCs）中引起了极大的兴趣。通过简单快速的一锅水相合成，使用辛基苯氧聚乙氧基乙醇（NP-40）作为结构导向剂，合成了平均直径为 2.3nm 的超薄 PdFePb 纳米线（NWs）。所制备的 PdFePb NWs 的电化学活性表面积（ECSA，121.18m²/mg）增加。对于乙二醇氧化反应（EGOR）和甘油氧化反应（GOR），PdFePb NWs 表现出更高的活性和更好的稳定性，优于自制的 PdFe NWs、PdPb NWs、商业 Pd 黑和 Pd/C（20wt%）。这些结果表明，超薄 PdFePb NWs 在增强多元醇电氧化方面具有极高的催化活性和耐久性。
