Highly efficient CuNi-ZrO₂ nanocomposites for selective hydrogenation of levulinic acid to γ-valerolactone.

ABSTRACT: CuNi-ZrO₂ nanocomposites were prepared by a simple coprecipitation technique of copper, nickel and zirconium ions with potassium carbonate. The structures of the nanocomposites were characterized by N₂ physical adsorption, XRD, H₂-TPR and STEM-EDS. The Cu_0.05Ni_0.45-ZrO₂ nanocomposite showed outstanding catalytic performance in hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL), especially NaOH solution (0.5 mol L^-1) as a solvent. 100% LA conversion and > 99.9% GVL selectivity are achieved over Cu_0.05Ni_0.45-ZrO₂ catalyst at 200 °C, 3 MPa for 1.5 h. Characterization results suggest that the excellent reactivity of the Cu_0.05Ni_0.45-ZrO₂ may
