METAL-CARBON NANOCOMPOSITE AND METHOD OF PREPARING SAID COMPOSITE Russian patent published in 2010 - IPC C08J5/00 B82B3/00 B82B1/00 B01J21/18 B01J23/40 C07C5/41 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of making nanostructured metal-carbon composite materials and can be used in heterogeneous and electrocatalysis. The metal-carbon nanocomposite contains metallic nanoparticles of alloys of Pt with a metal selected from Ru, Re, Rh, uniformly dispersed in the carbon matrix structure. The matrix is made from polyacrylonitrole which is pyrolysed through exposure to infrared light with intensity which corresponds to temperature of 650-1100°C. Total amount of metal equals 0.1-20% of the mass of the composite. The method of making a metal-carbon composite is based on reducing the said metals from solutions of their salts. A combined solution of metal salts, one of which is platinum and the other is either Ru or Re or Rh in an amide or sulfoxide solvent is added to polyacrylonitrile solution in the same solvent and undergoes pyrolysis while exposed to infrared light with intensity which corresponds to temperature of 650-1100°C.

EFFECT: obtained metal-carbon nanocomposites are active in a range of catalytic chemical conversions and can be used as heterogeneous catalysts, eg in dehydration of hydrocarbons and particularly dehydration of cyclohexane.
