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.

Light-driven primary amine oxidation to imines integrated with H2 production presents a promising means simultaneous of high-value-added fine chemicals and clean fuels. Yet, the effectiveness this strategy is generally limited by poor charge separation photocatalysts uncontrolled hydrogenation secondary amines. Herein, spatial decoupling proposed isolate redox chemistry at distinct sites photocatalysts, CoP core–ZnIn2S4 shell (CoP@ZnIn2S4) coaxial nanorods are assembled as proof-of-concept photocatalyst. Directional ultrafast carrier occurs between core ZnIn2S4 shell, confirmed in situ X-ray photoelectron spectroscopy, surface photovoltage transient absorption spectroscopy analyses. Toward photoconversion model substrate benzylamine N-benzylbenzaldimine, CoP@ZnIn2S4 exhibits 48-time higher rate >99% selectivity when compared (ca. 20% selectivity), detailed reaction mechanism has been verified diffuse reflectance infrared Fourier transform spectroscopy.

Solar photocatalysis is the most ideal solution to global energy concerns and environmental deterioration nowadays. The heterojunction combination has become one of successful effective strategies design manufacture composite photocatalysts. Heterojunction structures are widely documented markedly improve photocatalytic behavior materials by enhancing separation transfer photogenerated charges, widening light absorption range, broadening redox potentials, which attributed presence both build-in electric fields at interface two different complementarity between electron structures. So far, a large number have been reported applied for water splitting, reduction carbon dioxide nitrogen, cleaning, etc. This review outlines recent accomplishments in modification photocatalysts, aiming provide some useful perspectives future research this field.
