摘要： 本研究通过静电纺丝和分阶段热处理方法，在多孔碳纳米纤维(PCNFs)上制备了一系列不同合金比例的PtCu纳米合金催化剂，展示了合金颗粒表面形貌和Cu-Pt-Cu结构对HER的影响。结果表明PtCu添加量比为1:2时获得最佳析氢性能，酸性条件下10 mA cm-2过电位37mV，拥有良好的长期稳定性。本研究为PCNFs负载过渡金属与Pt的二元合金纳米催化剂提供一种新的制备方法。

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 were discovered. The study determined that the most effective hydrogen evolution performance was achieved using a PtCu additive mass ratio of 1:2 under acidic conditions, resulting in an overpotential of 37 mV at 10 mA cm-2 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.
