论文摘要
用于生产“绿色氢”的电化学水分拆分技术对于全球碳中立任务很重要。在高电流密度下具有不错的性能的电催化剂在该技术的工业实施中起着核心作用。近年来，该领域已经极大地发展，正如许多类型的催化剂所见证的，并合成了与工业相关的当前密度（> 200 MA CM-2）的工作。请注意，催化剂的活性和稳定性可能会受到其局部反应环境的影响，它们与当前密度密切相关。通过讨论该领域的最新进展，我们总结了几个关键方面，这些方面影响了高电流密度电催化的催化性能，包括催化剂的尺寸，表面化学，电子传输路径，形态和催化剂 - 电解质分解器相互作用。我们强调了多尺度设计策略，该策略全面考虑了这些方面，以开发高电流密度的催化剂。我们还提出了在这个新兴领域的未来方向上的观点。
Electrochemical water splitting technology for producing "green hydrogen" is important for the global mission of carbon neutrality. Electrocatalysts with decent performance at high current densities play a central role in the industrial implementation of this technology. The field has advanced immensely in recent years, as witnessed by many types of catalysts have been designed and synthesized which work at industrially-relevant current densities (> 200 mA cm-2). Note that the activity and stability of catalysts can be influenced by their local reaction environment, which are closely related to the current density. By discussing recent advances in this field, we summarize several key aspects that affect the catalytic performance for high-current-density electrocatalysis, including dimensionality of catalysts, surface chemistry, electron transport path, morphology, and catalyst-electrolyte interplay. We highlight the multiscale design strategy that considers these aspects comprehensively for developing high-current-density catalysts. We also put forward out perspectives on the future directions in this emerging field.
