METHOD FOR PRODUCTION OF GOLD-CARBON NANOSTRUCTURED COMPOSITE Russian patent published in 2017 - IPC H01G11/00 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention refers to the technology for preparing nanostructured composites based on highly porous carbon matrices filled with gold nanoparticles. A method for production of gold-carbon nanostructured composite includes preparation of highly porous carbon matrix by treatment of carbon material with alkali solution, recovery of nano-sized gold particles in pores of the obtained matrix by impregnation of a weighed amount of matrix with aqueous solution of precursor HAuCl₄ with subsequent heating, washing and drying. While preparing the carbon matrix, carbon material is treated with saturated alkali solution in weight ratio alkali : carbon material of (2.5÷4):1, the obtained highly porous carbon matrix is impregnated with the solution of precursor HAuCl₄ with concentration of 4.1⋅10^-3÷1.07⋅10^-1 mol/l.

EFFECT: invention allows to produce gold-carbon nanostructured composite with high specific surface and low gold content.
