Carbon Nano Tubes obtained from Plant Based Oil (Nigella sativa) and it's Hydrogen Storage Capacity

Vinod Lohakane | Sandesh Jaybhaye


Abstract: The spray pyrolysis technique of plant based oil i. e. Kalonji seed oil (Nigella sativa) at 800C temperature under inert gas atmosphere and in presence of Nickel catalyst, carbon nanotubes (CNTs) were obtained. In this paper we discussed the synthesis of CNT from Kalonji oil. The synthesis is carried out over Nickel catalyst by spray pyrolysis at 800C in an inert atmosphere of Hydrogen gas. The obtained CNTs were purified using diluted solution of 11 HCL HNO3 so as to remove the nickel catalyst and amorphous carbon. Then the obtained CNTs were characterized by using, SEM (Scanning Electron Microscope) X-ray Diffractometry. The specific surface area measurement of CNT was carried out by using adsorption of methylene blue (MB) dye and BET method. Both the results obtained from BET method and MB method was correlated. The amount of hydrogen stored by as grown CNT was measured by pressure method. We also studied the effect of pressure on the storage of hydrogen. The optimal hydrogen storage capacity was 0.8 wt. % at 11 kg/cm3 and 2.5 wt. % at 100kg/cm3.
