Preparation of Porous Carbon Nanofiber Loaded Copper-platinum Alloy Catalysts and Their Electrocatalytic Hydrogen Evolution Performance

doi:10.7503/cjcu20240042

Abstract

Abstract:

In this investigation， a series of PtCu nano-alloy catalysts with varying alloy ratios were prepared on porous carbon nanofibers（PCNFs） using electrostatic spinning and staged heat treatment methods. The effect of the geometrical morphology of the alloy particles and the Cu-Pt-Cu structure on the hydrogen evolution efficiency was discovered. The study determined that the most effective hydrogen evolution performance was achieved using a PtCu additive molar ratio of 1∶2 under acidic conditions， resulting in an overpotential of 37 mV at 10 mA/cm² and exhibiting robust long-term stability. This research presents an innovative approach for producing binary alloy nanocatalysts of PCNFs impregnated with transition metals and Pt.
