A series of electro-sorption equilibrium experiments have been performed to remove ions from aqueous solution, using two kinds of carbon aerogels as the electrodes. The experiment results showed that these two types of carbon aerogels with similar surface area but different pore size distribution performed differently. The combination of pore size distribution and electrolyte concentrations determines...
In this study, porous carbon aerogels are prepared by polycondensation of resorcinol and formaldehyde catalyzed by sodium carbonate followed by carbonization of the resultant aerogels in an inert atmosphere. Pore structure of carbon aerogels is adjusted by changing the molar ratio of resorcinol to catalyst during gel preparation and also carbonization under Ar and activation under CO2 atmosphere at...
Carbon nanotubes (CNTs) doped vanadium pentoxide (V2O5) porous aerogels are a good kind of material as the cathode material in lithium batteries due to their layered structure, high energy density, good reversibility, high capacity for lithium ion insertion. V2O5-CNTs nanocomposites were synthesized by a sol-gel method, using the solvent exchange and ambient pressure drying technique. Electrochemical...
Carbon aerogels are derived via a sol-gel process with resorcinol and formodehyde and subsequent pyrolysis of the precursor (RF) aerogels. Due to their high surface area, electrically conducting network and chemical inertness, carbon aerogels can be considered ideal electrodes in rechargeable batteries. In this paper the optimization of the preparation and structure controlling of carbon aerogels...
