Zeolite-templated carbons (ZTCs) are a class of porous carbons that have a designable structure with a high surface area and gravimetric storage capacity. However, for practical purposes volumetric storage capacity is a more important metric. To investigate this metric, we have worked with collaborators at Tohoku University to explore a novel densification procedure to remove interparticle space. ZTCs have been reported to demonstrate high mechanical strength and a resistance to pore deformation. The objective of this work is to understand how varying the compaction procedure affects the hydrogen and methane binding interactions within the ZTCs. This technique could improve the storage capacity beyond that of pure hydrogen or methane gas compression. The goal of my project has been to collect, model, and analyze adsorption equilibria on these unique samples by collecting measurements between 25 K and 298 K. This data has been collected using a custom Sieverts apparatus constructed for the purpose of performing high pressure isotherms. The Sieverts apparatus utilizes volumetric measurements by recording temperature and pressure changes between two well calibrated volumes. Using this data, the change in moles attributed to uptake by the sample can be measured. Compacted ZTCs seem to show a significant, reversible uptake of hydrogen; meaning they could be a candidate as an effective hydrogen storage material for mobile applications.
