Activated carbon hollow fibers (ACHFs) with high surface area were prepared from inexpensive, renewable ramie fibers (RFs) by a single-step activation method under lower temperature than that of other reports. The effects of activation conditions on the pore structure and turbostratic structure of ACHFs were investigated systematically. The results show that ACHFs surface area decreased but micropore...
Amphiphilic carbonaceous material (ACM), with nanoscale dispersion in alkaline aqueous solutions, is synthesized from green needle coke. As a special precursor with small particle size, plenty of functional groups and widened d 002 simultaneously, ACM guarantees subsequent ACM-based activated carbons (AACs) with high specific surface area over 3000m 2 g −1 as well as well-developed...
Amphiphilic carbonaceous material (ACM), which could be dispersed in alkaline aqueous solutions in nano-scale, was prepared by oxidation of green needle coke. Mesoporous activated carbon was then obtained by further KOH activation, named as AC-A. It was showed that AC-A was a mesoporous material with surface area and pore volume up to 3347 m2/g and 1.81 cm3/g. For its excellent pore structure and...
