Preparation of Porous Carbon with Controlled Pore Size Distribution by Polymerization-dependent Phase Separation Technique

Porous carbon was prepared by the polymerization-dependent phase separation technique. The characterizations of the porous carbon were determined with mercury porosimetry, scanning electron microscope and BET surface analyzer. The effects of various processing parameters (thermal process and the type of used glycols) on the properties of porous carbon were studied. The results show that porous carbon obtained is amorphous. The carbon particulate size and pore size decrease with increasing thermal polymer temperature, whereas porosities increase. When the thermal process [40℃(3h)→100℃(24h)] employed, the porous carbon is with average pore size of 1.75μm and porosity of 51.86%. By varying glycol; porous carbon with narrow pore size distributions can be obtained and the average pore size of porous carbon is between 0.01 and 5μm, with BET surface area range from 350 to 400m2·g-1.
