Preparation of activated mesocarbon microbeads with high mesopore content

In this study, activated mesocarbon microbeads (AMCMBs) with high mesopore content were prepared from the chemical activation of mesocarbon microbeads (MCMBs) with KOH. The resulting activated mesocarbon microbeads possess well-developed pore structure. The maximum value of the total pore volume is 2.45 cm(3)/g, and BET surface area can reach 3182 m(2)/g. Especially, the resulting mesoporous activated microbeads also have mesopore content ranging from 56.1% to 65.7%. It can be seen from the isotherms of N-2 at -196 degreesC that the resulting activated mesocarbon microbeads have high adsorption capacity. (C) 2003 Elsevier Science B.V. All rights reserved.
