ABSTRACT

An ultrathin sheet-like carbon nanostructure provides an important model of a two-dimensional graphite structurewith strong anisotropy in physical properties. As an easy and cheap route for mass production, RF thermal plasmasynthesis of freestanding carbon nanosheet from CH4 (Methane) and C3H8 (Propane) is presented. Using vapor synthesisprocess with RF inductively thermal plasma, carbon nanosheets were obtained without catalysts and substrates. Thesynthesized carbon nanosheets were characterized using transmission electron microscopy (TEM), Raman spectroscopy, Xraydiffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis. The carbon nanosheets synthesized using methane andpropane generally showed 5~6 and 15~16 layers with a wrinkled morphology and size of approximately 100 nm.
