한국어 초록
In this work, highly porous carbons were prepared by chemical activation of carbonizedbiomass-derived aerogels. These aerogels were synthesized from watermelon flesh using ahydrothermal reaction. After carbonization, chemical activation was conducted using potassiumhydroxide to enhance the specific surface area and microporosity. The micro-structuralproperties and morphologies were measured by X-ray diffraction and scanning electron microscopy,respectively. The specific surface area and microporosity were investigated byN2/77 K adsorption-desorption isotherms using the Brunauer-Emmett-Teller method andBarrett-Joyner-Halenda equation, respectively. Hydrogen storage capacity was dependent onthe activation temperature. The highest capacity of 2.7 wt% at 77 K and 1 bar was obtainedwith an activation temperature of 900°C.영어 초록
