The electrocatalytic oxidation of 2.5-dihydroxymethylfuran (DHMF) was carried out on platinum and nickel electrodes in alkaline medium. Suitable operating conditions of HPLC analyses were found to determine each reaction product formed during the anodic oxidation. When electrolysis was conducted on a bare Pt electrode or on a NiOOH anode, DHMF is converted only into 5-hydroxymethylfurfural (HMF). Conversely, the electrooxidation of DHMF on Pt, modified in situ by lead adatoms, yielded selectively 61% 2,5-furandialdehyde (FDC). In all the cases, HMF was the primary reaction product.
