Ni/C COMPOSITE PREPARATION AND INVESTIGATION OF THE CHARACTERISTICS OF ITS FORMATION ON POROUS CARBON SUPPORT

Abstract

The paper deals with the preparation of nanostructured metal-carbon composite metal nanoparticles by reduction of the iron subgroup (nickel), supported on a mesoporous carbon having a known pore size distribution. It is shown that the formation of metal on the carbon support in the reduction of nickel chloride with hydrazine in an alkaline environment is through the formation of intermediate nickel hydroxide. A method of nickel-carbon composites preparation by reduction of metal nanoparticles on the surface of the carbon support was developped.
