In order to obtain porous carbon materials with meso pores, Phenol-formaldehyde resin (PFR) containing sawdust was immersed in 50wt % KOH aqueous solution and heated to 973 -1223 K in N2 (PFR-saw dust). Meanwhile PF resin carbonized at 873K was mixed with an excess amount of KOH, and heated to 1073 K in N2 (PFR-KOH). The carbons thus obtained were investigated pore structure by measurement of BET surface area and pore-size distribution.
