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.
