Carbon Nano Materials (CNM) from biogenic carbohydrate rich non-edible precursors such as Syzygium cumini (Jamun), Tamarindus indica (Imli) and Litchi chinensis (Imli) seeds were synthesized by chemical vapour deposition method (CVD). Parameters were optimized by Taguchi optimization method, four parameters such as precursor, temperature, carrier gas and duration and three levels S. cumini, T. indica and L. chinensis as a precursor, Argon (Ar), Nitrogen (N2) and Hydrogen (H2) as a carrier gas, 1 hour (hr), 2 hours and 3 hours (hrs) for duration of pyrolysis, 800C, 900C and 1000C for temperature were selected. In the present work, impact of precursor is 35.84% which is the most effective factor than temperature (29.59%) and other parameters such as duration (19.50%) and the least effective factor is carrier gas (15.07%). Impact of parameter on the yield which described by the deviation of signal to noise (S/N) ratio. The result of deviation of S/N ratio shows T. indica seed (precursor), 900C (temperature), 2 hr (duration) and Ar (carrier gas) are the best parameters. The morphology of CNM is studied by SEM characterization and the nature of synthesized CNM by RAMAN spectroscopy.
