Silica and activated carbon were simultaneously produced from rice husk ash with K2CO3. The surface area and average pore size of the activated carbon were 1713 m(2)/g and 4 nm. The maximum adsorption capacity of activated carbon was 210 mg/g for methylene blue and the capacitance value reached 190 F/g. The yield of silica reached 96.84% and the particle size was 40-50 nm. Potassium carbonate could be recycled. The entire synthetic procedure was simple, environmental-friendly and economical-effectively. (C) 2012 Elsevier Ltd. All rights reserved.
