THE METHOD TO MODIFY THE STRUCTURE OF A CARBON NANOTUBE FOR HYDROGEN STORAGE BY ATMOSPHERIC PRESSURE PLASMA

摘要

Provided is a method for modifying a structure of carbon nanotube for hydrogen storage by using atmospheric pressure plasma, wherein carbon nanotube useful for material for hydrogen storage is etched with atmospheric pressure plasma so as to increase a capacity for hydrogen storage. The method for modifying a structure of carbon nanotube for hydrogen storage by using atmospheric pressure comprises etching a carbon nanotube to be used as material for hydrogen storage with atmospheric plasma so as to increase a capacity for hydrogen storage. Helium and argon which are reaction gases, and 2-10%(based on air) of oxygen as etching gas are added, in order to increase an etching effect with the atmospheric plasma. A carbon nanotube manufactured by the method has open ends, flawed wall, and numerous nano-sized pores.
