Production of graphene and nanoparticle catalysts supported on graphene using microwave radiation

摘要

Microwave irradiation is used to synthesize graphene and metallic nanocatalysts supported on graphene either by solid or solution phase. In solid phase methods, no solvents or additional reducing agents are required so the methods are “environmentally friendly” and economical, and the graphene and nanocatalysts are substantially free of residual contaminants. Recyclable, high efficiency Pd nanocatylysts are prepared by these methods.

1. A method of catalyzing chemical cross-coupling of at least two reactants of interest, comprising the steps of
producing a Pd catalyst comprising nanoparticulate Pd supported on graphene by irradiating a mixture of graphite oxide (GO) and Pd metal with microwave radiation, and combining said at least two reactants of interest in the presence of said Pd catalyst and under conditions which allow said Pd catalyst to catalyze said chemical cross-coupling of said at least two reactants of interest, wherein said chemical cross-coupling is a Heck cross-coupling reaction.
