Electrochemical reactions involving gaseous chemicals as reactants or products have the potential to play a critical role in 

transitioning to a sustainable, carbon-neutral society. Such reactions include gas-evolving reactions (e.g., the hydrogen 

evolution reaction (HER), oxygen evolution reaction, and chlorine evolution reaction) and gas-consuming reactions (e.g., the 

carbon dioxide reduction reaction, nitrogen reduction reaction, and oxygen reduction reaction). For efficient and stable 

production of desired chemicals via these reactions, it is imperative to develop rational strategies for managing gaseous 

chemicals, as well as properly design electrocatalysts. For gas-evolving reactions, efficient gas bubble removal from

electrodes is crucial, as gas bubbles can adhere to the electrodes, lowering efficiency and stability due to inefficient mass 

transport and repeated stress cycles. Conversely, gas-consuming reactions require an effective supply of gaseous reactants

and suppression of competing HER for efficient, selective target chemical production. In this review, we summarize recent 

studies on controlling the hydrophilic and hydrophobic microenvironment of electrodes to address these issues and suggest

characterization practices and future perspectives for practical applications. We believe this article provides valuable insights 

and will inspire researchers in various fields to design innovative electrochemical systems for carbon neutrality.
