Metal–Organic Framework-Stabilized CO2/Water Interfacial Route for Photocatalytic CO2 Conversion

Here, we propose a CO2/water interfacial route for photocatalytic CO2 conversion by utilizing a metal–organic framework (MOF) as both an emulsifier and a catalyst. The CO2 reduction occurring at the CO2/water interface produces formate with remarkably enhanced efficiency as compared with that in conventional solvent. The route is efficient, facile, adjustable, and environmentally benign, which is applicable for the CO2 transformation photocatalyzed by different kinds of MOFs.
