Abstract Recent years have witnessed an upsurge of interest in exploiting advanced photo‐/electrocatalysts for efficient energy conversion and environmental remediation. Constructing internal electric fields has been highlighted as a rising star to help facilitate various catalytic processes, with the merits promoting charge transfer/separation, optimizing redox potential creating effective active/adsorption sites. Internal are usually formed by polarization uneven distributions between different constituent layers, which widely exist piezoelectrics, polar surface terminations, heterostructure materials. Herein, groundbreaking interdisciplinary overview latest advances construction improve photo(electro)catalytic electrocatalytic activity is provided. This critical review begins encyclopedic summary classification, advantages, synthesis strategies fields. Subsequently, identification methods thoroughly discussed based on characterization techniques, experiments, theoretical calculations, can provide profound guidance in‐depth study To elaborate theory–structure–activity relationships fields, corresponding reaction mechanisms, modification strategies, performance jointly discussed, along discussion their practical applications. Finally, insightful analysis challenges future prospects field‐based catalysts discussed.
