Abstract
ABSTRACT Harnessing photothermal‐electronic coupling to accelerate surface redox kinetics represents a promising strategy for boosting photocatalytic CO 2 conversion efficiency. In this work, we construct a nanosheet‐hollow core‐shell ZnIn 2 S 4 @CeO 2 S‐scheme heterojunction via a facile hydrothermal approach, achieving the integration of efficient interfacial charge transfer with localized photothermal enhancement. Comprehensive characterizations and density functional theory calculations confirmed that the S‐scheme band alignment promotes directional charge migration and maintains strong redox potentials. Meanwhile, the engineered heterointerface and confined hollow cavity synergistically broaden light absorption, enrich CO 2 adsorption sites, and generate localized thermal fields that accelerate interfacial reaction kinetics. As a result, the ZnIn 2 S 4 @CeO 2 heterojunction exhibits a CO yield of 96.21 µmol g −1 h −1 with a selectivity of 87%, which is 2.87 and 7.81 times higher than that of pure ZnIn 2 S 4 and CeO 2 , respectively. This work offers a new design paradigm for photothermal‐assisted S‐scheme photocatalysts in solar‐driven CO 2 reduction.
