“…Manipulating fluid behavior such as distribution, absorption, and transport at the interface exhibits great opportunity to multiphase chemical reactions, especially in electrochemical systems. [1][2][3] Gas-involving electrochemical reactions, which refer to electrochemical processes that involve the participation or generation of gas species, play a significant role in various applications, including energy conversion and storage, [4,5] electrochemical sensors, [6,7] and environmental remediation. [8,9] According to the role of the gas in the reactions, gas-involving reactions are categorized as gas evolution reactions, including hydrogen evolution reaction (HER), oxygen evolution reaction (OER), chlorine evolution reaction (ClER), hydrazine oxidation reaction (HzOR), and urea oxidation reaction (UOR), and gas consumption reactions such as oxygen reduction reaction (ORR), nitrogen reduction reaction (NRR), and electrochemical acetylene reduction (EAR).…”

The manipulation of gas in multiphase interactions plays a crucial role in various electrochemical processes. Inspired by nature, researchers have explored bioinspired strategies for regulating these interactions, leading to remarkable advancements in design, mechanism, and applications. This paper provides a comprehensive overview of bioinspired gas manipulation in electrochemistry. It traces the evolution of gas manipulation in gas‐involving electrochemical reactions, highlighting the key milestones and breakthroughs achieved thus far. The paper then delves into the design principles and underlying mechanisms of superaerophobic and (super)aerophilic electrodes, as well as asymmetric electrodes. Furthermore, the applications of bioinspired gas manipulation in hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), and other gas‐involving electrochemical reactions are summarized. The promising prospects and future directions in advancing multiphase interactions through gas manipulation are also discussed.
