Abstract Rationally designing nanostructures based on a comprehensive understanding of structure‐property relationships is instrumental in enhancing the photothermal effect. Here, general two‐stage morphology‐structure‐control strategy presented to construct tandem built‐in electric fields (BIEFs) embedded hollow bifunctional photocatalysts (Sv‐chalcogenide nanocage/NiCo 2 S 4 heterojunctions, Sv represents sulfur vacancies, chalcogenides include ZnIn , CdS, CdIn ). This involves fabricating polyhedral cages via constraint epitaxy and embedding BIEFs (consisting intra‐component inter‐component BIEF) within nanocages through defect‐mediated heterocomponent anchorage. The resulting nanoreactors synergize multilight scattering/reflection with directional charge‐transfer boost photocarrier dynamics by stimulating plentiful carrier generation driving continuous localization delocalized‐electron transportation. Subsequently, localized surface plasmon resonance (LSPR)‐induced photogenerated electron excitation continuously collaborates intrinsic for hot generation, thus improving Heterojunctions efficient regulation optimize pivotal intermediate adsorption/activation selective alcohol oxidation coupled H evolution, delivering unprecedented reactivity broad substrate compatibility. study provides programmable framework structurally architectures, elucidating substantial impact morphology‐structure control molecular catalytic behavior.

Abstract Photocatalysis has shown power in the valorization of biomass while controlling selectivity is a long‐standing goal and challenge, especially for complex reactive bio‐polyols. The control photocatalytic biopolyols reforming to formic acid (FA) or CO realized via engineering electrostatic field on TiO 2 semiconductor. generated by surface modification with anion adsorbates, which can alter trap states photoexcited holes regulate interfacial hole transfer surface‐bound species, thereby strongly affecting activity. Taking dehydration as an example, shallow pristine favors FA CO, deep after introduced adsorbates makes stable. Based this result, successfully tuned oxidation field. A wide range be selectively converted into CO. This work presents effective strategy manipulate reaction pathways generating electric
