Abstract
Herein hydrogenolysis of biomass-derived 5-hydroxymethylfurfural (HMF) into 1,2,6-hexanetriol (1,2,6-HT) has been demonstrated using a MOF-derived Pt@Al2O3catalyst and NaBH4as the hydrogen source. The result showed a 63% 1,2,6-HT yield under relatively mild reaction conditions in aqueous media. Thein situmethod used for catalyst synthesis improved the homogeneous distribution of Pt species on the Al2O3support. The reaction pathway for the hydrogenolysis of HMF-to-1,2,6-HT conversion exhibited the formation of 2,5-bis(hydroxymethyl)-furan (2,5-DHF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (THFDM) intermediates. The kinetic study revealed that the activation energy of THFDM (78.7 kJ mol?1) is higher than that of 1,2,6-HT (64.7 kJ mol?1), indicating that lower reaction temperature favors the production of 1,2,6-HT. ?
