Structural properties of a series of commercial nongraphitized carbon blacks were studied by means of argon adsorption at 87 K and 77 K. The specific surface area of the samples was calculated using the standard BET method. The micropore volume and external surface area were both calculated by the αs-plot method. Pore volume and adsorption energy distributions were calculated numerically by using the regularization method. The above mentioned quantities obtained from argon adsorption isotherms were compared with those evaluated from nitrogen adsorption at 77 K.

Soft-templated microporous-mesoporous carbons with embedded alumina nanoparticles were synthesized using resorcinol and formaldehyde as carbon precursors, different inorganic acids as a catalyst and poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) block copolymer as a soft template. The carbons studied have very good adsorption properties such as high specific surface area, uniform pore size distribution and a large total pore volume. The choice of catalyst seems to play an important role for the incorporation of aluminum species to the carbon framework, which after thermal treatment form aluminum oxide nanoparticles. This simple approach seems to be very promising for the design of carbon-based materials for a broad range of applications.
