Efficient, stable electrocatalysts are required to promote the hydrogen evolution reaction (HER) to obtain hydrogen as a clean, sustainable fuel via water splitting. In the present work, ribbons of the metallic glass FeCoPC were produced using a conventional melt-spinning technique and assessed as electrocatalysts for HER. In 0.5 M HSO, these ribbons generated an overpotential of 118 mV at a current density of 10 mA cm. This overpotential remained essentially constant over 20 h under these conditions. On the basis of the excellent properties, these glassy ribbons represent a new type of highly active, robust HER catalyst suitable for practical applications.
需要高效、稳定的电催化剂来促进析氢反应（HER），通过水分解获得清洁、可持续的氢气作为燃料。在本工作中，采用传统的熔体纺丝技术制备了金属玻璃 FeCoPC 的带状样品，并将其作为 HER 的电催化剂进行了评估。在 0.5 M HSO 中，这些带状样品在 10 mA cm 的电流密度下产生 118 mV 的过电势。在这些条件下，过电势在 20 小时内基本保持不变。基于优异的性能，这些玻璃状带状样品代表了一种新型的高效、稳定的 HER 催化剂，适用于实际应用。
