摘要

Pt合金纳米结构已被探索作为甲醇氧化反应的有前途的阳极催化剂。然而，Pt催化剂仍然面临着尚未解决的挑战。研究表明，尺寸和几何结构会影响材料的催化活性，并与合成技术有关。在本研究中，在不同的合成时间下制备了PtPdNi纳米结构。FESEM结果表明，所有样品均呈现纳米池结构。合成时间为150s的PtPdNi对甲醇氧化表现出更高的催化活性和对一氧化碳中毒的抗性。

Rapid synthesis of trimetallic alloy PtPdNi nanosponges: structural, morphology and catalytic performance

Pt alloy nanostructures have been explored as promising anode catalysts for methanol oxidation reaction. However, the Pt catalyst have continued to face challenges that are yet to be resolved. Studies have shown that the size and geometric structure can influence a material’s catalytic activity and is related to the synthesis technique. In this study, PtPdNi nanostructures were produced at different synthesis duration. FESEM results show that all the samples exhibited nanosponges structure. The PtPdNi synthesized for 150 s, exhibited higher catalytically active toward methanol oxidation and resistance to carbon monoxide poisoning.
