Graphene was synthesized on transition metal scaffolding which serves as a catalyst.  Plasma is used as a means for creating high-internal-energy structures such as graphene or single walled nanotubes. The plasma is created at about 10 Torr pressure with an Astex 1500.  In lieu of a customized pattern deposited on a substrate, a Transmission Electron Microscopy (TEM) grid was used, 50-288-94 1000 mesh from Fisher Thermo Scientific. The result is Few-Layer Graphene (FLG) produced at a substrate temperature of 950 <sup>o</sup>C as estimated by optical two-color pyrometer.  The graphene takes the form of free standing walls, growing outward from the metal grid.  The grid spacing was thus 25.4 microns, and the square perforation was about 10 microns.  Using a mixture of hydrocarbons, a plasma was maintained for 10 minutes in order to create a uniform deposit of graphene with about 1.0 microns thickness, as shown by scanning electron microscopy.  The plasma is contained in a quartz tube, the outside of which is cooled by water flowing in copper tubing.  Energy Dispersive Spectroscopy (EDS) date shows a layer of titanium on the underside of the FLG layer, indicating strong adherence between the graphene and the metal.  This may imply that the unpaired pi-bonding electrons in graphene are able to make much stronger chemical bonds than the Van der Waals bonds that are left on the surface of crystalline graphite.  The ability to create highly patterned FLG has many applications, including the creation of ultra-black coatings. The photon absorbing properties of graphene make it of great interest for photovoltaic conversion, and in this case those attributes also make it of great interest to simply absorb broadspectrum photons and then dissipate the energy in the atomic plane. <br/>
