The main purpose of this work is to fabricate ordered uniform porous carbons and to test their usage in gas separation. The concerned problem statement includes irregular pores size distribution which will result poor selectivity during gas separation process. Therefore, the existence of ordered uniform network in porous carbon is important to overcome the poor selectivity issue. Porous carbons are remarkable due to the excellent absorption capability in their volume and surface. Ordered uniform porous carbons could be formed by template synthesis. Different template materials used for the template synthesis process will produce dissimilar porous carbons properties in term of specific surface area, pore diameter and pores distribution. The scope of study for this work concentrates on two main issues. First issue is the effect of template material's properties to the porous carbons fabrication. While another one involved application of the fabricated porous carbons in gas separation. The methodology of this work starts with preparation of carbon precursor. To be more specified, the preparation of carbon precursor includes synthesis of inorganic template and impregnate of the template with organic template. The impregnation of the templates means the precursor is polymerized. Subsequently, the carbon precursor would undergo carbonization process. The organic material is carbonized. The final stage of porous carbons fabrication is etching process. Through this process, the inorganic template is removed. Properties of the porous carbon are determined through characterization process using equipments such as X-ray diffraction (XRD) and Scanning Electron Micrograph (SEM). The application of fabricated porous carbons in this work could be proven by carbon dioxide, C02 gas separation using permeation cell.
