Abstract

Mesoporous carbon was prepared by a combined method of carbonization and activation processes, in which rice husk and KOH were used as carbon source and activator, respectively. Nitrogen adsorption-desorption isotherms (ADI) were measured by specific surface area instrument, the pore size distribution and pore volume were calculated by BET equation and BJH method. The mesoporous characteristic was characterized by small angle X-ray diffraction. The gas and solid composition from husk activation process was characterized by X-ray diffraction (XRD) and simultaneous thermal analysis mass spectrometry (TG-MS), then the pore forming mechanism was speculated. The results show that the average pore size of the prepared mesoporous carbon was as high as 4.54 nm and the specific surface area and mesopore rate were 2174.09 m2/g and 78.73 %, respectively. The K2Si4O9 was found in the activated rice husks, it may be from reaction SiO2 of rice husk with the decomposer K2O of KOH.
