| 제목 | Influence of pore-structure on VOC adsorption properties of multi-porous activated carbon powders |
| 초록 | Carbon has attracted more and more attention in scientific aspects and technological applications due to the diversity of structural and electrical properties. The forms of carbon include not only the crystalline phase of graphite, diamond and fullerene, but also many amorphous materials. As one of non-crystalline carbon, the activated carbon could be used as adsorption materials and catalyst due to their developed internal pore structure, huge surface area and presence of surface chemistry activity. Treatments such as thermal treatment and chemical treatment can modify the pore structure and the chemical nature of the activated carbon. The modification of activated carbon is an attractive route towards the novel application of these materials as gas-phase adsorbents, as well as catalyst supports. In this work, the influence of pore-structure on VOC absorption properties of multi-porous activated carbon powders was investigated with systematic structural investigation. The three different activated carbons with different porosity and surface area were selected. The samples exhibited almost amorphous carbon structure with small amount crystalline graphite. The specific surface area of the samples was measured by using BET analysis and was in the ranging between 1351 and 2245 m2/g. In detailed structural analysis, the three samples revealed the significant difference in specific surface area in micro-, meso- and macro-pore, which strongly influenced to the absorption properties of toluene that is one of the VOCs. |
