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

Abstract

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.
