/ Ni/ACTIVATED CARBON AEROGEL COMPOSITE FOR HYDROGEN STORAGE AND METHOD OF MANUFACTURING THEREOF

摘要

The present invention relates to a nickel/active carbon aerogel composite for storing hydrogen, and to a method for producing the same, wherein the nickel/active carbon aerogel composite has nickel introduced thereto. To provide a carbon aerogel composite having improved hydrogen adsorption amount compared to conventional active carbon aerogel, nickel nano-particles are introduced to carbon aerogel activated by KOH. According to the present invention, through a carbon aerogel activating method using KOH, a composite having a wide specific surface area can be produced. A dipping amount is controlled, and nickel nano-particles are introduced, so a nickel content of the composite can be easily and precisely controlled. Moreover, according to the present invention, a high ratio of nickel nano-particles can be introduced to carbon aerogel having a widened specific surface area due to activation. As the introduced nickel nano-particles serve as hydrogen-affinity adsorption points, nickel/active carbon aerogel composite for storing hydrogen can be produced under room temperature and high pressure conditions. Thus, useful properties are ensured in methodological terms of using hydrogen as an alternative energy.
