Title:
CERIUM OXIDE NANOPARTICLES, DISPERSION, OXIDIZING AGENT, ANTIOXIDANT, AND METHOD FOR MANUFACTURING CERIUM OXIDE NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2021/132628
Kind Code:
A1
Abstract:
The present invention addresses the problem of discovering cerium oxide nanoparticles having high oxidation performance and a dispersion including the same. Provided are cerium oxide nanoparticles and a dispersion including the same, the cerium oxide nanoparticles being manufactured by mixing a solution of an aromatic heterocyclic compound which does not have a substituent or which has at least one substituent selected from the group consisting of a methyl group, an ethyl group, an amino group, an aminomethyl group, a monomethylamino group, a dimethylamino group, and a cyano group and which includes 2-8 carbon atoms and 1-4 nitrogen atoms in the ring structure thereof, and a cerium (III) salt or a solution including cerium (III) ions, and adding an oxidizing agent.
