Nanoporous materials are potential candidates for catalytic supports toward water treatment, electrode materials for batteries, fuel cells, and supercapacitors, and drug delivery carriers. Particularly, nanoporous carbon (NPC) materials have recently attracted great interests due to their unique physical and chemical properties, e.g., excellent chemical and mechanical stability, good electrical conductivity, and high specific surface area. ZIF-67 derived NPC were prepared under different carbonization temperatures ranging from 800°C to 1000°C, and investigated the effect of the temperature on the porous structure. Raman analysis confirms that the graphitic degree of the obtained samples increased as the applied carbonization temperature is increased. With the gradual increase of the graphitic degree, the surface area is decreased. The results highlight how the pore-size distribution, surface area, and graphitic degree can simply be tuned by changing the carbonization temperature.
