Abstract
Detonation of hydrocarbon gaseous precursors with oxygen in a chamber is a cheap, green, and scalable technique for producing multilayer graphene aerosol gels. Here we describe mixing oxygen and acetylene in various ratios to explore the range of properties of the graphene aerosol gels produced. The properties and characteristics we studied include Raman spectra, XRD spectra, mass density, appearance, and specific surface area. The higher the oxygen content in the chamber, the higher the detonation pressure, mass density, and crystallinity, with lower yield, specific surface area, and defect in the sample. For all samples, Raman peak intensities 2D/G=0.5 matching bilayer graphene, as well as all peaks having Lorentzian shape and positioning consistent with that of single layer graphene.
