“…The control of the porous structure of carbon is of practical interest for different applications such as adsorbents for gas separation [1,2], electrode materials for energy storage [3][4][5], catalyst supports [6], packing materials for chromatography [7], host materials for gas storage [8], thermal and/or phonic insulators [9,10], etc. For many advanced applications such as double layer supercapacitors the control of porosity at nano-level is very essential.…”

Organic aerogels were synthesized by sol-gel polymerization of resorcinol (R) with formaldehyde (F) catalyzed by sodium carbonate (C) followed by vacuum drying. The influence of the resorcinol/sodium carbonate ratio (R/C) on the porous structure of the resultant aerogels was investigated. The nitrogen adsorption-desorption measurements show that the aerogels possess a well developed porous structure and mesoporosity was found to increase with increasing the R/C ratio. Carbon aerogels were obtained by carbonization of RF aerogels. The carbonization temperature impacts the microstructure of the aerogels by pore transformations during carbonization probably due to the formation of micropores and shrinkage of the gel structure. The results showed that a temperature of 1073 K is more effective in the development of the pore structure of the gel. Activated carbon aerogels were obtained from the CO 2 activation of carbon aerogels. Activation results in an increase in the number of both micropores and mesopores, indicative of pore creation in the structure of the carbon. Activation at higher temperatures results in a higher degree of burn off and increases the pore volume and the surface area remarkably without change of the basic porous structure, pore size, and pore size distribution.

“…For further elimination of residue of templates from carbon specimens, we have used a treatmant by ammonium chloride NH 4 Cl aqueous solution. In the NH 4 Cl treatment, approximately 0.1 g of each specimen and 0.5 g of NH 4 Cl are stirred in 100 ml ultra pure water for 0.5 h. After the treatment, the specimens are separated by filtration, and washed with ultra pure water for several times.…”

Porous ceramic materials are generally used for templates in synthesis of new porous carbon materials by template method. In the synthesis procedure, template materials are finally dissolved by acid or alkaline solution. Improvement of carbon content in the carbon materials by the process is expected to be effective for advancement of porosity and specific surface areas of the specimens, therefore realization of elimination of templates to a maximum extent is assumed to be desirable. In this report, we have prepared several porous carbon materials by the use of natural soils or clays for templates, and improved their carbon content by ammonium chloride NH 4 Cl treatment. However, their specific surface areas demonstrate a tendency to decrease contrary to the expectation. The result suggests that the original carbon specimens are rather effective in porosity, and the residue of templates can also play a useful part for specific surface areas of the carbon materials. This effect is attractive for improvement of synthesis process of porous carbon materials, which have high specific surface area, from viewpoints of practical applications.
