Hydrogen, as a clean and renewable energy source, is a promising candidate to replace fossil fuels and alleviate the environmental crisis. Compared with the traditional H-type cells with a finite-gap, the design of membrane electrodes can reduce the gas transmission resistance, enhance the current density, and improve the efficiency of hydrogen production. However, the harsh environment in the electrolyser makes the membrane electrode based water electrolysis technology still limited by the lack of catalyst activity and stability under the working conditions. Due to the abundant active sites and structural flexibility, amorphous nanocatalysts are alternatives. In this paper, we review the recent research progress of amorphous nanomaterials as electrocatalysts for hydrogen production by electrolysis at membrane electrodes, illustrate and discuss their structural advantages in membrane electrode catalytic systems, as well as explore the significance of the amorphous structure for the development of membrane electrode systems. Finally, the article also looks at future opportunities and adaptations of amorphous catalysts for hydrogen production at membrane electrodes. The authors hope that this review will deepen the understanding of the potential of amorphous nanomaterials for application in electrochemical hydrogen production, facilitating future nanomaterials research and new sustainable pathways for hydrogen production.
氢作为一种清洁的可再生能源，是替代化石燃料和缓解环境危机的有前途的候选者。与具有有限间隙的传统H型电池相比，膜电极的设计可以降低气体传输阻力，提高电流密度，并提高制氢效率。然而，电解槽中的恶劣环境使得基于膜电极的水电解技术仍然受到工作条件下催化剂活性和稳定性不足的限制。由于具有丰富的活性位点和结构灵活性，非晶态纳米催化剂是替代方案。在本文中，我们综述了非晶态纳米材料作为膜电极电解制氢电催化剂的最新研究进展，阐述并讨论了它们在膜电极催化体系中的结构优势，以及探讨非晶态结构对膜电极体系发展的意义。最后，本文还展望了非晶态催化剂在膜电极制氢方面的未来机遇和适应性。作者希望这篇综述将加深对非晶态纳米材料在电化学制氢中应用潜力的理解，促进未来纳米材料的研究和新的可持续制氢途径。
