Abstract

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.
