Abstract

Methods and apparatuses to produce graphene and nanoparticle catalysts supported on graphene without the use of reducing agents, and with the concomitant production of heat, are provided. The methods and apparatuses employ radiant energy to reduce (deoxygenate) graphite oxide (GO) to graphene, or to reduce a mixture of GO plus one or more metals to produce nanoparticle catalysts supported on graphene. Methods and systems to generate and utilize heat that is produced by irradiating GO, graphene and their metal and semiconductor nanocomposites with visible, infrared and/or ultraviolet radiation, e.g. using sunlight, lasers, etc. are also provided.
