Abstract

Post synthetically-modified UiO-66-NH₂ with a molecular cobaloxime [Co(DMG)₂Cl₂] (DMG = dimethylglyoxime) catalyst displays excellent photo-(404 μmol g⁻¹ h⁻¹) and electrocatalytic H₂ evolution activity in an aqueous solution. Several analytical and spectroscopic methods, including femtosecond transient absorption spectroscopy and DFT, revealed the unique interaction between cobaloxime and the MOF leading to enhanced catalytic activity.
