METHOD OF PRODUCING CATALYST FOR PROTIUM-DEUTERIUM ISOTOPIC EXCHANGE Russian patent published in 2013 - IPC B01J21/18 B01J23/50 B01J37/00 B22F9/24 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to heterogeneous catalysis, particularly a method of producing a catalyst for protium-deuterium isotopic exchange. The method involves obtaining metal nanoparticles while reducing metal ions in a reverse micellar solution which consists of a solution of a metal salt which is RhCl₃ or RuOHCl₃, a surfactant which is bis(2-ethylhexyl) sodium sulphosuccinate and a nonpolar solvent, isooctane, followed by deposition onto a support which is Sibunit, wherein silver nanoparticles are obtained by preparing reverse micellar solutions of rhodium or ruthenium in molar ratio of the aqueous solution of the metal salt to the surfactant ranging from 1:1 to 10:1, and a water-alcohol solution and an ammonia solution are then added in amount of 5-50 wt % and 10-30 wt %, respectively, after which the suspension undergoes ultrasonic treatment, deaeration and exposure to γ-radiation of ⁶⁰Co with a dose ranging from 1 to 40 kGy.

EFFECT: invention enables to obtain a catalyst having high catalytic activity and meant for operation in the 77-400 K temperature range.
