Title
Immobilized PVA-stabilized gold nanoparticles on silica show an unusual selectivity in the hydrogenation of cinnamaldehyde
Abstract

This work reports for the first time an “unusual” property of immobilized PVA-stabilized gold nanoparticles (AuNPs) on SiO2 for highly selective hydrogenation at the CC bond of cinnamaldehyde (CAL) at 150–180 °C, uncovering a catalytic route for selective hydrocinnamaldehyde (HCAL) production from CAL. When the same colloidal gold nanoparticles are immobilized on ZrO2, they effect competitive hydrogenations at both CC and CO bonds of the CAL molecules under identical reaction conditions.
