Published: March 16, 2025

Abstract Overall artificial photosynthesis, as a promising approach for sunlight-driven CO 2 recycling, requires photocatalysts with efficient light adsorption and separate active sites coupling H O oxidation. Here we show In-based metal–organic framework (MOF) heterostructure, i.e., In-porphyrin (In-TCPP) nanosheets enveloping an In-NH -MIL-68 (M68N) core, via facile one-pot synthesis that utilises competitive nucleation growth of two organic linkers In nodes. The coherent interfaces the core@shell MOFs assure structural stability which will function heterojunctions to facilitate transfer photogenerated charge overall photosynthesis. In-TCPP shell in heterostructure improves capabilities visible absorption enhance photocatalytic reduction. Simultaneously, In-O M68N core efficiently catalyze oxidation, achieving high yields HCOOH (397.5 μmol g −1 h ) (321.2 under focused sunlight irradiation. superior performance this coupled its straightforward synthesis, shows great potential mitigating carbon emissions producing valuable chemicals using solar energy.
