The metal–carbon–fluorine system for improving hydrogen storage by using metal and fluorine with different levels of electronegativity

摘要: Abstract In order to improve the capacity of hydrogen storage using activated carbon nanofibers, metal and fluorine were introduced into nanofibers by electrospinning, heat treatment, direct fluorination. The pore structure samples was developed KOH activation process investigated nitrogen isotherms micropore size distribution. specific surface area total volume approached 2800 m2/g 2.7 cc/g, respectively. Because electronegativity gap between two elements (metal fluorine), electron a molecule can be attracted one side. This reaction effectively guides nanofibers. amount dramatically increased in this metal–carbon–fluorine system; content as high 3.2 wt%.
