摘要

The electrocatalytic performance of nanomaterials can be enhanced by finetuningthe coordination environment and number of low-coordination atoms.Confinement engineering is the most effective strategy for the precise chemicalsynthesis of electrocatalysts through the modulation of electron transferproperties, atomic arrangement, and molecular structure in a confined region.It not only alters the coordination environments to adjust the formationmechanism of active centers, but also regulates the physicochemical propertiesof electrocatalysts. Consequently, the nucleation, transportation, and stabilizationof intermediate species in electrocatalysis are optimized, and thenimprove the performance covering activity, stability, and selectivity. In thisreview, confinement engineering is introduced in terms of confined definition,classification, construction, and basic principles. Then, the latest advancesin the confinement engineering of electrocatalysts for the oxygen reductionreaction, hydrogen evolution reaction, oxygen evolution reaction, nitrogenreduction reaction, and carbon dioxide reduction reaction are systematicallyevaluated. Furthermore, using representative experimental results and theoreticalcalculations, the structure-activity relationships between confinementengineering and electrocatalytic performance are illustrated. Finally, potentialchallenges and future development prospects of confined electrocatalysts arehighlighted, with a focus on controlling the construction of confined environments,investigating uncommon catalytic properties in confined regions, andpractical applications.
