Insights into influences of nanoparticle size and metal-support interactions of Cu/ZnO catalysts on activity for furfural hydrogenation

Abstract

Cu/ZnO catalysts mainly derived from aurichalcite with Cu/Zn=0.4-1.1 (mol/mol) were prepared via “decrease pH” coprecipitation method and introduced in furfural hydrogenation to furfuryl alcohol. The “precursor effect” was clearly confirmed and the catalyst with a Cu/Zn=0.8 was provided with the best conversion and TOF. Catalysts were characterized via XRD, FT-IR, N2O-titration, TEM, H2-TPR, XPS and AES. The size of Cu nanoparticles and Cu-ZnO interaction were systematically investigated and were found to consumingly influencing catalytic activity of the catalysts. As the result, the best catalytic performance of the catalyst with Cu/Zn=0.8 was due to its not only suitable Cu particle size (8nm) but also strong metal-support interactions (SMSI) acting as the Cu-ZnO synergy.
