A method of modifying a porous structure inorganic membranes of carbon nanomaterials

摘要

1. A method of modifying a porous inorganic membrane structure carbon nanomaterial comprising depositing carbon produced during pyrolysis of hydrocarbons to the surface of macropores workpiece, characterized in that the preparation of the substrate is carried out by impregnating solution of catalyst precursor liquid-phase synthesis of the carbon nanomaterial on a substrate of porous material, whereupon the substrate heat treatment and at a temperature carbonaceous pyrolysis gas leads to deposition of carbon nanomaterial floor cheniya carbon material layer a predetermined thickness. ! 2. A method of modifying a porous inorganic membrane structure carbon nanomaterial according to claim 1, characterized in that the hydrocarbon gas pyrolysis process is carried out at a temperature of 600-1000 ° C. ! 3. A method of modifying a porous inorganic membrane structure carbon nanomaterial according to claim 1, characterized in that as precursor use aqueous solutions of metal nitrates of the second group with the addition of citric acid and ethylene glycol. ! 4. A method of modifying a porous inorganic membrane structure carbon nanomaterial according to claim 1, characterized in that on the opposite side of the substrate precursor solution was applied at various concentrations.
