Impact of Biomass Derived Raw Material on Nitrogen Doped Porous Carbon Structure

Carbon compounds with large surface area can be used as electrocatalytic cathodes for fuel cells. Nitrogen atoms largely determine the properties of doped activated carbon, such as hardness, wear resistance, electrical resistance etc., and therefore there is a need for new scientific information on the properties and structure of modified carbon matrix. Wood char and activated carbons based on wood char, cellulose, black liquor, and fine cellulose sludge were obtained in different activation conditions and doped with dicyandiamide. The obtained N-doped carbon materials porous structures were compared taking into account preparation conditions and raw material.
