Abstract

Porous carbon material is one of the most common and very important for various applications thank to its high surface area and adsorption capability. In this study, mesoporous carbon was prepared by thermal decomposition of copper-based metal-organic framework MOF-199 under inert atmosphere and followed by immersing in diluted HNO₃ solution in order to remove metal/metal oxide and activation of the resultant porous carbon. Scanning electron microscopy (SEM) revealed that as-prepared material remained intact octahedral morphology of pre-pyrolysis MOF structure, and product has spongy structure with specific surface area of 375 m²/g as measured using N₂ adsorption isotherm (BET), which can be employed as an effective adsorbent.
