采用阳极氧化铝电沉积技术成功制备了具有高电化学活性表面积的钯纳米线阵列（NWAs）。Pd NWAs对乙醇电氧化的电催化活性和稳定性不仅明显高于传统的Pd膜电极，而且也高于成熟的商用PtRu/C电催化剂。Pd - NWAs作为直接乙醇燃料电池碱性介质中乙醇电氧化的电催化剂具有很大的潜力。
Pd nanowire arrays (NWAs) with high electrochemically active surface area (see figure) are successfully fabricated using anodized aluminum oxide electro-deposition. The electrocatalytic activity and stability of the Pd NWAs for ethanol electrooxidation are not only significantly higher that of conventional Pd film electrodes, but also higher than that of well-established commercial PtRu/C electrocatalysts. The Pd NWAs show great potential as electrocatalysts for ethanol electrooxidation in alkaline media in direct ethanol fuel cells.
