Sunlight-driven simultaneous CO2 reduction and water oxidation using indium-organic framework heterostructures

Abstract Overall artificial photosynthesis, as a promising approach for sunlight-driven CO 2 recycling, requires photocatalysts with efficient light adsorption and separate active sites for coupling with H 2 O oxidation. Here we show a In-based metal–organic framework (MOF) heterostructure, i.e., In-porphyrin (In-TCPP) nanosheets enveloping an In-NH 2 -MIL-68 (M68N) core, via a facile one-pot synthesis that utilises competitive nucleation and growth of two organic linkers with In nodes. The coherent interfaces of the core@shell MOFs assure the structural stability of heterostructure, which will function as heterojunctions to facilitate the efficient transfer of photogenerated charge for overall photosynthesis.…
