摘要
铂基纳米材料的催化性能主要取决于它们的尺寸,结构和组成,对于这些因素的合理调控有助于设计高活性的电催化剂。~([1-3])此处,我们发展了一种水相合成方法用于室温下一步合成三金属的AuPdPt纳米线,整个过程不需要任何模板,种子,有机溶剂或高温操作。碱性条件下的乙二醇氧化测试表明,相对于商业化的铂碳催化剂,我们所合成的材料展现出较好的电化学活性和稳定性,这种良好的催化性能可归功于其独特的纳米线结构和多组分间的协同效应。~([4-5])
The catalytic performance of Pt-based nanomaterials mainly depends on their size, structure and composition, and the rational control over these factors is very critical for designing highly effective electrocatalysts. Herein, we develop an aqueous solution method for one-step synthesis of trimetallic Au PdP t nanowire at room temperature, and the whole process does not need any templates, seeds, organic solvents or high-temperature operation. Electrochemical tests show that the as-prepared catalysts exhibit improved activity and stability toward ethanol oxidation in alkaline solution compared with commercial Pt/C catalyst, which can be ascribed to the unique nanowire structure and multi-component synergistic effect.
