Abstract

A maximum of 8.75 wt% hydrogen adsorption was observed by carbon fibers which were obtained by the pyrolysis of cotton. Cotton was pyrolysed at 750°C for 3 h in argon atmosphere. Carbon fiber was soaked with 0.1M Ni(NO). This was filtered and dried at 100°C. Finally, metal nitrate treated carbon fibers were heated at 850°C for 3 h in argon atmosphere. Carbon fibers thus obtained were found to absorb hydrogen to the extent of 8.75 wt%. Taguchi optimization technique was adopted to find out the best parameters responsible to give highest hydrogen adsorption. Carbon fibers that showed 8.75 wt% hydrogen adsorption were characterized by SEM, TEM, XRD, and Raman analysis.
