Study on the Preparation of Phenolic Resin-Based Porous Carbon Materials

In the experiment,adopting phenolic resin(PF)as carbon precursors and polyvinyl butyral(PVB)as pore former,porous carbon materials are prepared by blend carbonization,and the effect of the content of pore former PVB,carbonization temperature and carbonization time on BET specific surface area and pore structure of porous carbon materials are also studied.The results show that when the content of pore former PVB is 40%,carbonization temperature is 700℃ and carbonization time is 1.0 h,we can prepare porous carbon materials with 540.4 m2·g-1of specific surface area,0.37 cm3·g-1of pore cubage and 7.298 nm of average aperture.
