论文摘要
已知气泡会影响气体不断发展的电极中的能量和传质。但是，我们对气泡演化过程和电化学现象之间的复杂依赖性缺乏详细的理解。这篇评论讨论了我们当前对气泡对电化学系统影响的知识，目的是确定机会并激发该领域的未来研究。我们首先提供了与电化学过程有关的气泡演化物理学的基本背景。然后，我们概述了气泡如何影响电极过程的能源效率，详细介绍了气泡引起的对激活，欧姆和浓度过电势的影响。最后，我们描述了减轻损失以及如何利用气泡以增强电化学反应的不同策略。
Bubbles are known to influence energy and mass transfer in gas evolving electrodes. However, we lack a detailed understanding on the intricate dependencies between bubble evolution processes and electrochemical phenomena. This review discusses our current knowledge on the effects of bubbles on electrochemical systems with the aim to identify opportunities and motivate future research in this area. We first provide a base background on the physics of bubble evolution as it relates to electrochemical processes. Then we outline how bubbles affect energy efficiency of electrode processes, detailing the bubble-induced impacts on activation, ohmic and concentration overpotentials. Lastly, we describe different strategies to mitigate losses and how to exploit bubbles to enhance electrochemical reactions.
