Microstructure and Adsorption Property of Bamboo-Based Activated Carbon Fibers Prepared by Liquefaction and Curing
Keywords:Bamboo, activated carbon fibers, adsorption, microstructure, porosity
AbstractIn this study, activated carbon fibers (BACF) were prepared from moso bamboo by phenol liquefaction, spinning, curing, and CO2 activation. The microstructure and porous texture of BACF were investigated by Fourier transform IR spectroscopy, X-ray diffraction, and N2 adsorption at -196°C. The surface area and pore volume increased progressively after activation, and yields were found in the range of 39-59.6%. BACF showed type I isotherms with multimodal pore size distributions in the <6-nm region. It is believed that liquefied bamboo could be a suitable precursor for activated carbon fibers. The obvious change was not observed on the functional groups of BACF during activation. At the same time, it was found that the higher temperature improved the crystallite size and activation reaction of BACF.
