The highly efficient electrocatalytic oxidation of 5-hydroxymethylfurfural on copper nanocrystalline/carbon hybrid catalysts: structure–function relations

The Cu species in Cu(NSD)/CP exhibit a high electrochemical specific surface area, which allows efficient transformation from Cu 0 and Cu 1+ species to Cu 2+ with high catalytic capacity, resulting in excellent catalytic performance (96% yield of FDCA).
