Effect of Vanadium Nano-fibrous Flowers as being decorated on Carbon Nano Materials for Enhancing its Hydrogen Storage Capacity

Abstract: To enhance hydrogen storage capacity of Carbon Nano Materials (CNMs), Transition metal Vanadium in its Nano form at different concentrations on CNMs were synthesized from natural waste, Sugar-Cane Bagasse (SCB). Raw Carbon obtained by pyrolyzing SCB at high temperature in an inert medium and activated by alkali were decorated with Vanadium Nano-fibrous Flowers (V-NFs) (The authors named this as ‘Vanadium Nano-fibrous Flowers’) by annealing at different temperatures in CO2 atmosphere. XRD and Raman spectroscopic analysis were carried out for its structural elucidation. EDAX and ICP-AES gave the amount of Vanadium being deposited. Nano-fibrous Flowers of Vanadium on porous morphology of CNMs was depicted by SEM analysis. Comparative studies of Hydrogen adsorption of CNMs were concluded by Sievert’s apparatus for various concentration of vanadium on CNMs.
