Notes:
We used ethylene glycol as pore-forming agent to prepare porous carbon withinterconnected pores derived from phenol–formaldehyde resin. The mixture of resins and glycol wasby polymerization and pyrolysis monolithic material of porous carbon with interconnected mesoporesand a narrow pore size range. The average pore size of the porous carbon obtained was 28.2 nm. Thenitrogen adsorption isotherm for the porous carbon exhibited type IV isotherm, which correspondedto mesoporous adsorption. The method could endow porous carbon with BET surface area and porevolume about 500 m2/g and 0.607 cm3/g, respectively. The mesopores in porous carbon formed as aresult of phase separation of resin-rich phase and glycol-rich phase at polymerization and remove ofglycol-rich at subsequent pyrolysis
