METHOD OF PREPARING CARBON- AND METAL-CONTAINING NANOSTRUCTURES FROM AROMATIC HYDROCARBONS Russian patent published in 2004 - IPC

FIELD: organometallic products. SUBSTANCE: invention relates to physical chemistry of nanostructures and colloid systems and can be utilized in preparation of coatings, sorbents, and catalysts. Copper or aluminum foil is used as substrate. Aluminum foil is pretreated electrochemically in CuSO₄ solution, foil functioning as cathode therein, or anodized for 1 h in 20% H₂SO₄ at 20 C, voltage 15 v, and current density 2 A/sq.dm. Foil is covered with reaction mixture containing aromatic hydrocarbon (e.g. anthracene), AlCl₃, NaCl, and NiCl₂ at molar ratio 1:10:10:2, or aromatic hydrocarbon and polyvanadic acid at molar ratio 1:1. The total is then heated to temperature not superior to 160 C. Resulting nanostructure films are characterized by good adhesion to substrate. Nanostructures may be in the form of bundles of nanotubes and turbulence splices arranged an different angles to substrate. EFFECT: optimized preparation procedure. 7 cl, 6 dwg, 4 ex
