FIELD: chemistry.

SUBSTANCE: invention relates to heterogeneous catalysis, particularly a method of producing a catalyst for ortho-para conversion of protium. Described is a method of producing a catalyst for ortho-para conversion of protium, involving obtaining metal nanoparticles by reducing metal ions under the effect of y-radiation of ⁶⁰Co in a reverse micellar solution consisting of a metal salt solution, a surfactant which is sodium bis(2-ethylhexyl)sulphosuccinate, and a nonpolar solvent, isooctane, followed by depositing on a support, wherein the support used is Sibunit, and the metal salt used is RhCl₃ or RuOHCl₃, and reverse micellar solutions of rhodium or ruthenium are prepared in molar ratio of aqueous metal salt solution to surfactant ranging from 1:1 to 10:1; a water-alcohol solution is then added in amount of 5-50 wt % and ammonia solution is added in amount of 10-30 wt %, followed by ultrasonic treatment, deaeration and exposure to y-radiation of ⁶⁰Co with a dose of 1-40 kGy.

EFFECT: obtaining a catalyst with high activity and capable of operating in the temperature range of 77-110 K.
