Porous hard carbon prepared from polymeric precursor for hydrogen storage |
| 초록 |
In this study, activated polymer-based hard carbons were prepared using various steam activation conditions in order to enhance their hydrogen storage ability, and the adsorption characteristics of the porous carbons were investigated. The N2 adsorption isotherm characteristics at 77 K were confirmed by BET, BJH and NLDFT equations. The hydrogen storage behaviours of the porous carbons at 298 K and 100 bar were studied using a Pressure-Composition-Temperature apparatus. From the results, specific surface areas and total pore volume of the activated carbons were determined to be 1680–2320 m2/g and 0.78–1.39 cm3/g, respectively. The hydrogen adsorption of APHS-9-4 increased about 30% more than that of hard carbon. This indicates that hydrogen storage could be a function not only of specific surface area or total pore volume, but also of micropore volume fraction or the average pore size of adsorbents. |
