Utilization of γ-radiation in the synthesis of bimetallic Cu–Ni catalysts for selective vapour phase hydrogenation of levulinic acid to γ-valerolactone

Abstract

A set of mono and bimetallic Cu-Ni supported on γ-alumina catalysts were synthesized by utilizing γ-radiation instead of conventional calcination and reduction. Using a variety of characterization approaches, the structural...

Synthesis of Metallic Nanostructures Using Ionizing Radiation and Their Applications

“…Recently, bimetallic Cu-Ni systems supported on γ-alumina catalysts were synthesized using γ-radiation instead of conventional calcination and reduction and tested for the vapor phase selective hydrogenation of levulinic acid to γ-valerolactone. The γ-irradiated catalysts demonstrated a higher hydrogenation activity and stability than conventionally synthesized catalysts; the high activity was attributed to high copper dispersion and well-interactedCu-Ni metallic species [114].…”
