High Yield Electrooxidation Of 5-Hydroxymethyl Furfural Catalysed By Unsaturated Metal Sites In Cofe Prussian Blue Analogue Films

Prussian Blue Analogues (PBAs) are promising electrocatalysts for oxidation reactions due to their binary metal composition and tuneable redox properties. Herein, we report the generation of coordinative unsaturated metal sites in pulse electrodeposited (PED) CoFe PBAs for the oxidation of 5-hydroxymethylfurfural (HMF). The high reactivity by unsaturated metal sites, thoroughly characterized by a suite of spectroscopic techniques, results in a catalyst with superior activity towards the oxidation of HMF to 2,5 furandicarboxylic acid (FDCA).
