Selective Electrogenerative Oxidation of 5‐Hydroxymethylfurfural to 2,5‐Furandialdehyde

2,5-furandialdehyde (DFF) was synthesized by electrogenerative oxidation of 5-hydroxymethylfurfural (HMF) over a PtRu catalyst with 89 % selectivity at 50 °C after 17 h. This approach opens an avenue for a selective, energy-efficient and green oxidation of biomass-derived platform alcohols to added-value chemicals.
