Abstract

Using Graphene quantum dots (GQDs) functionalized gold nanoparticles (GQDs/AuNPs) as catalyst, hydrogen peroxide as oxidant, under different PH conditions and reaction time, the hellebore alcohol can be oxidized into hellebore aldehyde or hellebore acid with high activity and selectivity. However, GQDs/AuNPs show excellent dispersibility in aqueous solution which makes the recycle of catalyst be problem. In this work, the GQDs/AuNPs were further immobilized onto the prepared silicon dioxide by two methods of In-situ synthesis and physical adsorption dependently to get novel composites. It has been proved that the as-obtained composites can be used as heterogeneous catalysts for the oxidation of hellebore alcohol with comparable activity and better recycling ability of bare GQDs/AuNPs.
