Process for preparing nanoparticles of nickel monooxide of high catalytic activity

摘要

The process for preparing nanoparticles of the nickel with high catalytic activity resides in the fact that the reaction an aqueous solution of a photochemically and / or radiochemically sensitive compound containing nickel ions with the addition of scavengers -OH radical which is preferably selected from the group consisting of aliphatic alcohols or polyvinyl alcohol, or salts of organic acids containing anion -COO.sup .-. n., irradiated by UV radiation or gamma radiation of energy greater than 1 MeV or by accelerated electrons with energy 1-6 MeV dose of 5-150 Gy to give a finely dispersed solid phase of nickel oxide, solid phase is separated by ultrafiltration and dried at 100 degC and then the heat treatment at 200 to 600 degC.
