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. The structural characteristics of the activated carbons were observed by XRD and Raman spectroscopy. The N2 adsorption isotherm characteristics at 77K were confirmed by BET, BJH and NDFT equations. The hydrogen storage behaviours of the activated carbons at 298K and 10 MPa were studied using a PCT 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. In the observed result, the hydrogen adsorption of APHS-9-4 increased about 30% more than that of as-prepared hard carbon. This indicates that hydrogen storage capacity could be a function not only of specific surface area or total pore volume, but also of micropore volume fraction in the range of 0.63 to 0.78 nm of adsorbents. |
