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.
