MESOPOROUS PAN-ACF PREPARED BY KOH REACTIVATION

PAN ACF activated by steam was used as starting material, which was reactivated by KOH. The porous structures and adsorption performance were investigated by nitrogen isotherms adsorption on the bases of α s plot and DFT. It was shown that the specific surface area and pore volume increased after PAN ACF was reactivated by KOH, especially, the mesopore volume increased markedly up to 50?% of whole pore volume. There was no macropore occurring during the activation process.
