氧还原反应(ORR)、析氧反应(OER)、析氢反应(HER)等涉及气体的电化学反应是节能、环保的能量转换和存储技术的关键过程，受到越来越多的关注。开发相应的电催化剂是提高其电催化性能的关键。人们在开发先进的电催化剂方面付出了巨大的努力，以克服动力学上的迟滞。另一方面，电极界面结构在实际应用中也起着同样重要的作用，因为这些势在必行的电极反应通常在气体、液体电解质和固体电催化剂的三相界面上进行。一个理想的体系结构应该有利于发生在三相界面上的复杂反应，包括质量扩散、表面反应和电子转移。本文从三相界面的电极反应过程出发，系统地总结了优化气载型电催化三相界面的一些设计原则和合成策略。它可以分为三个主要的优化方向：暴露活性中心、促进质量扩散和加速电子转移。此外，我们还特别突出了几项在特定能量转换设备方面进行综合优化的出色工作，包括金属空气电池、燃料电池和水分离设备，并展示了极高的效率。最后，对未来的展望和挑战进行了展望。
Gas-involving electrochemical reactions, like oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER), are critical processes for energy-saving, environment-friendly energy conversion and storage technologies which gain increasing attention. The development of according electrocatalysts is key to boost their electrocatalytic performances. Dramatic efforts have been put into the development of advanced electrocatalysts to overcome sluggish kinetics. On the other hand, the electrode interfaces-architecture construction plays an equally important role for practical applications because these imperative electrode reactions generally proceed at triple-phase interfaces of gas, liquid electrolyte, and solid electrocatalyst. A desirable architecture should facilitate the complicate reactions occur at the triple-phase interfaces, which including mass diffusion, surface reaction and electron transfer. In this review, we will summarize some design principles and synthetic strategies for optimizing triple-phase interfaces of gas-involving electrocatalysis systematically, based on the electrode reaction process at the three-phase interfaces. It can be divided into three main optimization directions: exposure of active sites, promotion of mass diffusion and acceleration of electron transfer. Furthermore, we especially highlight several remarkable works with comprehensive optimization about specific energy conversion devices, including metal-air batteries, fuel cells, and water-splitting devices are demonstrated with superb efficiency. In the last section, the perspectives and challenges in the future are proposed.
