Synthesis and Characterisation of Carbon Nano Materials from Plant Derivative

Abstract

Abstract-Latex of Calotropis was used as precursor for synthesis of Carbon Nano material (CNM) by chemical vapour deposition (CVD) / pyrolysis process. Impact of different carrier gases (Hydrogen, Argon) and catalyst (Nickel, Cobalt, Iron) on morphology of CNM was assessed. It was found that Pyrolysis in presence of Hydrogen produced more defined Carbon Nano beads (10 nm to 900 nm) than with Argon which produced agglomerated clusters of spherical nano particles. So far as catalysts are concerned, Nickel gave better Carbon nano beads.Index Terms-Carbon nano material, carrier gas, latex of calotropis, metal nanocatalyst, pyrolysis.

Preparation of Fe-intercalated Graphite Based on Coal Tailings, Dimensional Structure

“…The greater the percentage of iron is added to the result in the morphology of graphite becomes more coarses and pores become larger. Compared with studies that have been reported (Viswanathan, 2014), which has conducted the synthesis and characterization of carbon nano-materials of Calotropis latex using iron, graphite of coal tailings produce rougher surface and uneven surfaces.

“…In addition, superconducting states of YbC6 and CaC6 are obtained at higher temperatures of Tc=6.5 K and T6=11.5 K (Weller et al, 2005), respectively, due to a strong electronphonon coupling (Valla et al, 2009). Previous studies have reported that graphite source derived from natural materials as graphite nano-sized materials (Mopoung, 2011 andViswanathan, 2014). The most important issue in the synthesis of graphite one of which is the cost of production, in addition to the quality, and methods of synthesis.…”
