Domino Upgrading of Hemicellulose Derivatives Using a Novel Magnetically Recoverable Mo(V)-Containing Heteropolyacid Catalyst
A catalyst composed of a sulfated zirconia-12-molybdophosphoric acid system supported on iron oxide nanoparticles has been synthesized, fully characterized, and evaluated for the domino conversion of hemicellulosic biomass-derived compounds to alkyl levulinates. The sulfation of the zirconia-12-molybdophosphoric acid generated Mo(V) species that are crucial for the material’s catalytic activity. The role of each component of the final material was evaluated, and this novel catalyst showed extraordinary activity in the upgrading of furfural and furfuryl alcohol to isopropyl levulinate via the employment of 2-propanol as a solvent, reagent, and hydrogen donor. Notably, the recyclability of the catalyst was evaluated, and comprehensive deactivation studies provided key insights into the process mechanism.
