Highly efficient hydrogenation of furfural to furfuryl alcohol over Cu-Al₂O₃-ZnO catalyst.

ABSTRACT: The development of simple, efficient and economical catalysts for the hydrogenation of biomass to produce high value-added chemicals is of great significance in solving the energy crisis. In this work, a series of non-precious metal catalysts (Cu-Al₂O₃-ZnO) with different defect sites were prepared by etching Devarda's alloy. Under optimized mild reaction conditions, the furfural conversion and furfuryl alcohol selectivity are both greater than 99.0%, and the catalyst has good reusability. Characterisation and experiments were used to investigate the activate species for hydrogenation reaction. It can be proved that the low-valent Cu species in the Cu-Al₂O₃-ZnO catalysts play an important role as adsorption and dissociation sites for H₂
