The production of γ-valerolactone (GVL) receives increasing attention due to its extensive applications as a promising fuel and fuel additive. In this study, the direct conversion of biomass-derived furfural to GVL with a unprecedent yield of 90.5% was achieved via consecutive hydrogenation and acid-catalyzed reactions over CuAl for hydrogenation and a co-catalyst (i.e. H-ZSM-5) for acid-catalysis in ethanol. The relative abundance of the hydrogenation sites and acidic sites determines the reaction network and the transfer of the main products from furfuryl alc. (FA) to Et levulinate (EL) or GVL, as the acidic sites, especially the Bronsted acidic sites, not only catalyze the formation of EL from FA, but also affect the hydrogenation activity of CuAl. However, the Lewis acidic sites facilitate the opening ring of FA to 1,4-pentanediol, preventing the GVL formation. The acid catalyst and hydrogenation catalyst deactivate via varied mechanisms in the conversion of furfural to GVL, which is required to be considered in the further development of the robust catalysts.
