FIELD: production of porous materials. SUBSTANCE: invention relates to porous carbon materials suitable to be used as adsorbents and catalyst carriers. Material constitutes a three-dimensional matrix formed by carbon layers with true density 1.8-2.1 g/cu.cm and following structural characteristics: d 002 = 0.340-0.349 nm, L= 4-18 nm, L= 3.5-14 nm. Carbon layers are tape-shaped with width 10000-50000 nm and thickness 30-159 nm. Tapes are connected and branched in nods and are spatially arranged as three-dimensional lattice with internodal distance 80-500 mcm, cell area 8000-200000 sq. mcm and space density 0.01-0.08 g/sq.cm. Tapes have curving and tubular shape. They are made up of microcrystallites of graphite-like carbon oriented to the surface with end facets. Basal planes of microcrystallites are chiefly oriented in perpendicular to longitudinal axis of tape and form ordered in direction [001] regions 1-15 nm in size. EFFECT: created new modification of high-porosity carbon material with ordered microstructure of surface. 4 cl, 1 tbl, 5 dwg |
