Abstract
The development of advanced technology for producing high-purity and low-cost hydrogen is crucial for the upcoming hydrogen economy. One of the most promising technologies to achieve carbon peak and carbon neutrality is hydrogen production through water electrolysis coupled with renewable energy. However, the efficiency of water electrolysis is limited by the catalyst material employed, thereby the pursuit of highly efficient catalysts is of paramount scientific significance. In this review, we focus on the synthesis of electrocatalysts for the hydrogen/oxygen evolution reaction (HER/OER) through various strategies such as hydrogen spillover, heterostructure construction, element doping, monatomic construction, LDH structure modification, high entropy alloy, and other approaches. The article also provides a comprehensive overview of the challenges encountered in enhancing the activity, stability, and durability of transition metal heterogeneous catalysts for both HER and OER. Moreover, the mechanisms of HER and OER are illustrated. The electrocatalysts prepared by these strategies have exhibited promising results in terms of water splitting performance. However, there are still unresolved issues that need to be addressed, such as improving long-term stability and reducing overall cost. Future prospects include exploring new materials and optimizing the preparation methods to further enhance the electrocatalytic activity.
开发生产高纯度、低成本氢气的先进技术对于即将到来的氢经济至关重要。实现碳峰值和碳中和的最有前途的技术之一是通过电解水和可再生能源制氢。然而,水电解的效率受限于所使用的催化剂材料,因此追求高效催化剂具有极其重要的科学意义。在这篇综述中,我们重点介绍了通过氢溢出、异质结构构建、元素掺杂、单原子构建、LDH 结构修饰、高熵合金等各种策略合成氢/氧进化反应(HER/OER)电催化剂的方法。文章还全面概述了在提高 HER 和 OER 用过渡金属异质催化剂的活性、稳定性和耐久性方面所遇到的挑战。此外,文章还阐述了 HER 和 OER 的机理。通过这些策略制备的电催化剂在水分离性能方面取得了可喜的成果。然而,仍有一些问题需要解决,如提高长期稳定性和降低总体成本。未来的前景包括探索新材料和优化制备方法,以进一步提高电催化活性。
