FIELD: chemistry.
SUBSTANCE: method of producing nano-sized Pt-Ni catalyst involves preparation of a mixture of starting compounds - carbonaceous material, hexachloroplatinic acid, a nickel salt in a solution containing ethylene glycol, adding to the mixture of starting compounds an alkali solution, reducing Pt and Ni metals, cooling the mixture to room temperature, washing and drying the catalyst. The ethylene glycol solution also contains ethyl alcohol in accordance with 2-3 parts of ethylene glycol and 1-2 parts of ethyl alcohol. Pt and Ni metals are reduced by adding to the solution 1M sodium boron hydride in 1M sodium hydroxide solution for 1-1.5 hours, and the mixture is treated with ultrasound while bubbling inert gas through the mixture. The carbonaceous material used is Vulcan XC-72 soot or nanotubes, or nanofibre. The inert gas used is argon, helium or neon.
EFFECT: shorter time and low power consumption of the process of producing the catalyst.
