Abstract
The electrocatalytic oxidation of 2.5-dihydroxymethylfuran (DHMF) was carri ed out on platinum and nickel electrodes in alkaline medium. Suitable opera ting conditions of HPLC analyses were found to determine each reaction prod uct 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-hydr oxymethylfurfural (HMF). Conversely, the electrooxidation of DHMF on Pt, mo dified in situ by lead adatoms, yielded selectively 61% 2,5-furandialdehyde (FDC). In all the cases, HMF was the primary reaction product.
