Onofre Casanova, Sara Iborra and Avelino Corma Biomass into Chemicals: Aerobic Oxidation of 5-Hydroxymethyl-2-furfural into 2,5-Furandicarboxylic Acid with Gold Nanoparticle Catalysts ChemSusChem 2
Cerious chemistry: 5-hydroxymethyl-2-furfural is selectively converted into 2,5-furandicarboxylic acid in water, using air as oxidant, under mild conditions, and with gold nanoparticles supported on nanoparticulate ceria (Au-CeO2) as catalyst. The catalyst is stable and reusable. Substrate degradation is strongly diminished and catalyst life is increased by performing the reaction in two temperature steps. The catalytic performance of Au-CeO2 surpasses that of other gold nanoparticle catalysts (e.g., Au-TiO2, Au-Fe2O3).
