摘要

利用氢进化反应(HER)通过电催化水分裂生产氢(H2)燃料,成本低廉,性能优越,且具有显著的稳定性。另一个关键因素是创新具有出色稳定性和高效率的良好电催化剂,这一点非常重要,而且在过去几十年中,氢进化反应的实际应用仍面临挑战。由于气泡释放、质子扩散和电子转移,氢在 HER 电极上产生。在建造和开发电极时应注意这些因素。本综述概述了作为电催化剂基础的各种电极的最新进展,如泡沫镍、钛箔、泡沫铜、泡沫碳等,还讨论了它们的 HER 催化活性,重点关注气泡释放、离子扩散、电极结构以及配方和制备过程。最后,我们概述了进一步改进和解决 HER 电极制造中重大问题的思路。

Recent Development of Electrodes Construction for HER in Electrocatalytic Water Splitting

Recent Development of Electrodes Construction for HER in Electrocatalytic Water Splitting

Production of hydrogen (H2) fuel using the hydrogen evolution reaction (HER) through electrocatalysis of water splitting is inexpensive, has optimal performance, and offers remarkable stability. Developing electrocatalysts with excellent stability and high efficiency has been a significant and challenging factor for practical applications of HER for decades. Hydrogen generation occurs on the HER electrode due to the emission of bubbles, proton diffusion, and the transfer of electrons. These considerations should be taken into account during the construction and development of the electrode. This review offers a synopsis of recent advancements in various electrodes used as a base for electrocatalysts, such as nickel foam, titanium foil, copper foam, carbon foam, and others, and discusses their HER catalytic activity, with a focus on the emission of bubbles, diffusion of ions, the structure of the electrode, and the formulation and preparation process. In conclusion, we provide an overview of ideas to further improve and address the significant issues in the manufacture of HER electrodes.
