Nitrogen (N2) adsorption/desorption isotherms of PC-X (porous carbon materials obtained at various temperatures)

These data contain nitrogen (N2) adsorption/desorption isotherms of PC-700 (porous carbon obtained at 700 °C), PC-800 (porous carbon obtained at 800°C), PC-900 (porous carbon materials obtained at 900°C). Data showed typical type-I isotherms, indicating the presence of micropores in their structures. PC-900, compared with PC-700 and PC-800, showed a higher N2 adsorption capacity, which meant that there were more microporous structures in PC-900.
