Activated ordered mesoporous carbons with a channel structure (AOMCs-CS) were successfully prepared byimposing CO2 activation on ordered mesopore carbon C-FDU-15. It is found that the continuous carbon frameworkof the precursor C-FDU-15 plays an important role in keeping the order structure of the resulting AOMCs-CS. Themild activation (e.g., 31 wt % burnoff) does not impair the order degree. After that, the order degree gradually decreaseswith further increasing burnoff. However, the basic hexagonal mesostructure of C-FDU-15 can still be found in theAOMCs-CS when the burnoff is up to 73 wt %, although many carbon walls are punched and thus many largermesopores and marcropores are generated. With increasing burnoff, the surface area and volume of microporesincrease first and then decrease, and the surface area and volume of mesopores continuously increase. The highestmeasured Brunaruer-Emmett-Teller (BET) surface area, micropore volume, and total pore volume of the AOMCs-CS reach 2004 m2/g, 0.50 cm3/g, and 1.22 cm3/g, respectively.
