“…Nano-restricted water, in addition to studying the density, electrical conductivity and other physical properties of water, one of the research directions should be the structure of the bilayer, and it has been found [47] that there is specific adsorption in the inner bilayer with weak receptor sites. This adsorption can change the local concentration in the nano-restricted volume, while the layers of nano-restricted space overlap on both sides of the wall if the radius of the nano-restricted space is less than half the thickness of the bilayer.…”

Electrocatalysis is an important energy conversion and storage technology that has made significant progress in areas such as fuel cells, hydrogen production from electrolyzed water and electrochemical synthesis. In practical applications, the efficiency and stability of electrocatalytic processes remain challenging. Spatially confined (or called domain‐limited) water refers to the immobilization of water molecules in a limited region near the catalyst surface to form a specific aqueous phase environment. This domain‐limited aqueous phase environment can greatly influence the electrocatalytic efficacy by enhancing adsorption and lowering the proton transport and solvent diffusion energy barriers in the reaction. In recent years, the goal of improving electrocatalytic performance has been successfully achieved through interfacial domain‐limited, microporous domain‐limited and nanoreactor domain‐limited. Spatially domain‐limited water as a novel strategy can significantly enhance the activity and selectivity of electrocatalytic reactions, but understanding its mechanism of action remains a challenge. With a deeper understanding of domain‐limited water and further development of the technology, it is believed that it will bring greater breakthroughs and application prospects in the field of electrocatalysis.
