The solid materials for hydrogen adsorption including carbonaceous materials, metal-organic frameworks, and zeolites have been extensively investigated to increase their specific surface area (SSA) and porosity to maximize the amount of hydrogen uptake onto the materials. Most of the effort in this field has focused on developing the porosity of the materials. However, the hydrogen uptake of the materials depends not only on the SSA but also on its surface characteristics, if not more so, which effect on the interaction between adsorbent (storage materials) and adsorbate (hydrogen molecules). To understand these factors in detail, we undertook an investigation to study the hydrogen uptake, the surface functionality and textural property of oxygen-rich porous carbons prepared by carbonization and subsequent activation using cigarette butts as a precursor. In this work, we also suggested the efficiency factor of the pore size of the materials for hydrogen adsorption. |
