  • Production of graphene and nanoparticle catalysts supported on graphene using laser radiation
    Patent number: 9768355
    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.
    Type: Grant
    Filed: December 10, 2010
    Date of Patent: September 19, 2017
    Assignee: Virginia Commonwealth University
    Inventors: M. Samy El-Shall, Victor Abdelsayed, Saud I. Al-Resayes, Zeid Abdullah M. Alothman
  • Production of Graphene and Nanoparticle Catalysts Supported on Graphene Using Microwave Radiation
    Publication number: 20150087498
    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 nanocatalysts are prepared by these methods.
