摘要

近年来，为阴离子交换膜燃料电池（AEMFC）中的氢氧化反应（HORs）寻找低成本、地球资源丰富的催化剂的工作取得了重大进展，但非铂族金属催化剂在操作条件下的稳定性仍然面临挑战。Zhou 等人在《自然-能源》（Nature Energy）杂志上发表的研究提出了一种创新方法，即利用量子约束效应抑制镍氧化，从而提高氢氧化还原镍（Ni）催化剂的稳定性和性能。这项研究不仅解决了镍基催化剂的表面钝化问题，还为设计用于能源转换技术的先进催化剂提供了新的可能性。

Quantum confinement for stable nickel catalyst in hydrogen oxidation

The quest for low-cost, Earth-abundant catalysts for hydrogen oxidation reactions (HORs) in anion-exchange membrane fuel cells (AEMFCs) has led to significant advancements in recent years, yet challenges pertaining to the stability of non-platinum-group metal catalysts operational conditions still remain. The study by Zhou et al. in Nature Energy presents an innovative approach to enhance the stability and performance of nickel (Ni) catalysts for the HOR by using quantum confinement effects to suppress Ni oxidation. This research not only addresses surface passivation of Ni-based catalysts but also unlocks new possibilities for designing advanced catalysts for energy conversion technologies.
