Abstract
A series of hydroxyapatite (HAP) supports with different Ca/P ratios were synthesized to prepare the MnOx/HAP catalysts. A MnOx/HAP catalyst showed highly efficient conversion of 5-hydroxymethylfurfural (HMF) into 2, 5-diformylfuran (DFF) in toluene solvent under no-alkali condition. 86.4% conversion of HMF with 90.9% selectivity of DFF at 120 °C for 12 h under 1.0 MPa O2 over the MnOx/HAP-10.0-400 were obtained. The redox of Mn4+/Mn3+ improved the oxidation of 5-HMF to DFF by the lattice oxygen, and the lattice oxygen was replenished by adsorbing O2 molecules. The reusability tests were found the catalyst could be reused up to four cycles without notable loss of catalytic activity. The MnOx/HAP-10.0-400 was a stable and reusable material for further industrial exploration of DFF in an environmentally friendly way.Description
