Abstract

Platinum nanoparticles coated with an imidazolium-based cross-linked polymer (with chloride as the counter anion) efficiently catalyze the oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid in water under mild conditions using oxygen as the oxidant. In this paper we explore this catalyst system by varying the counter anion, i.e. replacing chloride by BF4-, PF6-, bis(trifluoromethylsulfonyl)imide, hexanoate or laurate anions, in the cationic polymer. The counter-anion influences both the structure of the obtained platinum nanoparticles and their catalytic activity. Highest reaction rates were obtained with the weakly-nucleophilic bis(trifluoromethylsulfonyl)imide anion leading to complete conversion of the substrate and a high yield of 2,5-furandicarboxylic acid under mild conditions.
