METHOD OF PRODUCING CATALYST FOR PROTIUM-DEUTERIUM ISOTOPIC EXCHANGE AND ORTHO-PARA CONVERSION OF PROTIUM Russian patent published in 2013 - IPC B01J21/04 B01J23/50 B01J37/00 B22F9/24 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to heterogeneous catalysis, particularly to a method of producing a catalyst for protium-deuterium isotopic exchange and ortho-para conversion of protium. The method involves obtaining silver nanoparticles by radiochemical reduction of silver ions from a reverse micellar solution followed by deposition on an Al₂O₃ support, wherein the reverse micellar solution of silver is obtained from 0.02-0.5 M solution of bis(2-ethylhexyl) sodium sulphosuccinate in a non-polar solvent and 0.003-2.0 M aqueous solution of AgNO₃; the prepared solution is treated with ultrasound until a reverse micellar dispersion is obtained, followed by dearation thereof, after which the suspension is exposed to γ-radiation of ⁶⁰Co with a dose of 5-30 kGy.

EFFECT: invention enables to obtain a catalyst for operation at temperatures maximally close to liquefaction temperatures of protium and deuterium.
