Abstract：
Green hydrogen from electrolysis of water has attracted widespread attention as a renewable power source. Among several hydrogen production methods, it has become the most promising technology. However, there is no large-scale renewable hydrogen production system currently that can compete with conventional fossil fuel hydrogen production. Renewable energy electrocatalytic water splitting is an ideal production technology with environmental cleanliness protection and good hydrogen purity, which meet the requirements of future development. This review summarizes and introduces the current status of hydrogen production by water splitting from three aspects: electricity, catalyst and electrolyte. In particular, the present situation and the latest progress of the key sources of power, catalytic materials and electrolyzers for electrocatalytic water splitting are introduced. Finally, the problems of hydrogen generation from electrolytic water splitting and directions of next-generation green hydrogen in the future are discussed and outlooked. It is expected that this review will have an important impact on the field of hydrogen production from water.
摘要：
来自电解水的绿色氢作为可再生动力来源已经引起了广泛的关注。在几种制氢方法中，它已经成为最有前途的技术。然而,目前还没有能够与传统化石燃料制氢竞争的大规模可再生制氢系统。可再生能源电催化水裂解是一种理想的生产技术，具有环境清洁保护和良好的氢气纯度，符合未来发展的要求。这篇综述从三个方面总结和介绍了水裂解制氢的现状:电力、催化剂和电解质。特别是,主要动力源的现状和最新进展，介绍了电催化水分解的催化材料和电解槽。最后,讨论和展望了电解水分解制氢的问题以及未来下一代绿色氢气的发展方向。预计该综述将对从水中制氢的领域产生重要影响。
