Functionalized CNF for H2 adsorption study

The hydrogen is a clean source of fuel which when combusted under the presence of oxygen , it produces water vapour as the only exhaust gas. Besides that , the chemical energy density of hydrogen is about 142Mj/kg which is at least three times larger than that of other chemical fuels. Hence , in search of green alternative to replace gasoline , hydrogen has been proposed as ideal source of energy. However , the hydrogen volume is about 3000 times higher than that of gasoline at room temperature and atmosphere because it’s a molecular gas. Thus , the storage of hydrogen is the main drawbacks for further improvement of hydrogen technology. Therefore , on board hydrogen energy storage need compact , light , safe and affordable containment and the US Department of Energy states to achieve a 6.5% storage capacity. Hydrogen storage in functionalized carbon nanomaterial’s is a very attractive field since high gravimetric storage capacities maybe possible owing the low specific weight and high specific surface area to volume ratio and by functionalization ,it can be modified to increases certain functional groups which has the ability to attract and store hydrogen.
