Due to easily available in nature with plenty of abundance, and being a rich source of carbon, it can be used as organic precursor for the synthesis of Multiwalled carbon nanotubes (MWCNTs). In this study, we experimented the synthesis MWCNTs by using spray pyrolysis of neem oil over cobalt catalyst under the influence of argon atmosphere at 850 ° C. As synthesized MWCNTs were purified using acid treatment and characterized for structural confirmation. The electronic properties of as synthesized and purified MWCNTs was studied using four probe method. We studied the influence of acid treatment to MWCNTs on Surface area, Electrical properties and Hydrogen gas adsorption.
