Looks like could do at home. 70c, Near platinum quality ?

maybe increase the surface area of the graphene base , using a magnetic field before mixing in the cobalt?

They typically grow sheet on SiC, but hear you can plate any metal under current by just flowing methanol over it.

a straightforward synthesis that requires no explosive hydrogen or methane gas flow. The synthesis is further simplified by using only a liquid carbon source such as methanol. Of over a dozen liquid carbon sources studied, methanol is found to be unique in that it acts as both a carbon/hydrogen source and an inhibitor to amorphous carbon growth. No deposition of amorphous carbon was observed, regardless of vapor pressure, unlike methane and other hydrocarbons. Finally, we describe a protocol to control graphene growth to a single side or selected location on the copper substrate, which is required for most device applications.

can also use a press mill on poly, then burn the poly off.

another method with a ball mill

could prob put it straight on paper with silver acetate as a base...
