FIELD: chemistry.
SUBSTANCE: method for carbon material preparation includes carbonisation of the high-ash biomass in the air or inert atmosphere, carbonised biomass mixing with carbonate of alkaline metal or with carbonates mixture of alkaline metals in powder form at mole ratio carbonate of alkaline metal/silicon dioxide of the carbonised biomass equal to (1:1) - (1:5), heat treatment of the mixture at 700-1000°C in the inert atmosphere, washing and drying.
EFFECT: obtaining of the material with high textural properties from cheap plant raw materials.
