Abstract
A high-efficiency and low-cost Zr-based metal–organic frameworks loaded with Co catalyst for the catalytic transfer hydrogenation of biomass-derived 5-hydroxymethylfurfural (HMF) into 2,5-dihydroxymethylfuran (DHMF) through Meerwein–Ponndorf–Verley reduction was developed. A series of Co/UiO-66-NH2 catalysts were synthesised by wet impregnation and reduction using the KBH4 method and characterized by XRD, ICP-OES, XPS, SEM, TEM, BET and TPD techniques. As expected, Co1.6/UiO-66-NH2 displayed high catalytic transfer hydrogenation activity with 92.6% HMF conversion and 95.9% DHMF selectivity at a relatively mild reaction temperature (100 °C) in the presence of isopropanol that served as both hydrogen donor and reaction solvent. The highly dispersed Co species may effectively regulate the acid–base sites of the catalyst, which could be the main reason for the high hydrogenation activity.
