Abstract

Hydrogen is the most promising energy carrier to replace fossil fuels due to its sustainability, environmental friendliness, and high energy efficiency. Green electricity can be used to power electrocatalytic water splitting, which produces green hydrogen. The industrial production of green hydrogen is critical to achieving carbon-neutrality. Herein, we have systematically summarized industrial electrolyzers and related mechanisms for the OER and HER in both alkaline and acid media. Then, catalyst design strategies for achieving industrial current density are discussed, followed by the illustration of bubble growth and the principle of catalyst stability. Recent advances in long-term water electrolysis under both traditional laboratory and quasi-industrial conditions are also discussed. Besides, scale-up methods and low-cost catalysts are studied to accommodate industrial manufacturing. Finally, challenges and perspectives of industrial green hydrogen production are highlighted. This review would provide useful insights into the mechanism, design, fabrication, improvement, and application of electrocatalysts for industrial hydrogen production.

工业条件下电解水制氢的非贵金属基催化剂

氢具有可持续性、环保性、高能效等优点，是替代化石燃料的最有前途的能源载体。绿色电力可以用来为电催化水分解提供动力，产生绿色氢。绿色氢的工业生产对实现碳中和至关重要。在此，我们系统地总结了工业电解槽及其在碱性和酸性介质中OER和HER的相关机理。然后，讨论了实现工业电流密度的催化剂设计策略，接着说明了气泡生长和催化剂稳定性原理。讨论了在传统实验室和准工业条件下长期电解水的最新进展。此外，还研究了规模放大方法和低成本催化剂，以适应工业制造。最后，强调了工业绿色制氢面临的挑战和前景。本文将对工业制氢电催化剂的机理、设计、制造、改进和应用等方面提供有益的见解。
