Nanostructured porous carbons derived from biomass for gas storage |
| 초록 |
Nanostructured activated carbons were prepared by using natural resource and chemical activation treatment. In this work we used walnut as a carbon precursor and KOH as an activating agent. To examine the relationship between the surface heterogeneities as well as the textural properties of the adsorbents and their gas storage abilities, especially, three different carbonized weight ratios were applied for synthesizing the natural resource based ACs. The prepared AC samples were characterized by using nitrogen adsorption. The BET specific surface areas and the total pore volumes of the samples were in the range of 2000–2500 m2/g and 0.9-1.5 cm3/g, respectively. The hydrogen adsorption capacity was measured at 77 K and pressure up to 1 atm in an automatic volumetric device. We found that the textural properties of the ACs prepared were greatly dependent on the KOH ratios. Moreover, the hydrogen storage amounts were closely related with the microporous textural characteristics. |
