Mild and selective transfer hydrogenation of biomass-derived furfural to furfuryl alcohol over Cu/ZnO/Al₂O₃ with methanediol as the hydrogen donor

Abstract

A green catalytic transfer hydrogenation (CTH) strategy was developed for the continuous conversion of furfural (FF) to furfuryl alcohol (FFA) with Cu/ZnO/Al2O3 (CZA) as the catalyst under mild conditions. Methanediol...

Effect of Calcination Atmosphere on the Performance of Cu/Al2O3 Catalyst for the Selective Hydrogenation of Furfural to Furfuryl Alcohol

“…The reason for the increased yield was ascribed to the boosted generation of the surface Cu + /Cu 0 active sites and the promoted gaseous hydrogen dissolution in ethanol media by K 2 CO 3 . Cheng et al [ 36 ] developed a new catalytic transfer hydrogenation (CTH) strategy for the continuous conversion of FAL into FA with Cu/ZnO/Al 2 O 3 as the catalyst under mild conditions. The highly dispersive Cu species (Cu 0 , Cu + ), with few Lewis acidic sites and η 1 (O)-type adsorption, ensured high selectivity and mild conversion.…”
