Title:
PARTICLES FOR EXHAUST GAS PURIFICATION CATALYST
Document Type and Number:
WIPO Patent Application WO/2022/158270
Kind Code:
A1
Abstract:
Provided are particles for an exhaust gas purification catalyst, the particles comprising: inorganic oxide particles; and an inorganic coating layer covering the inorganic oxide particles. The particles for an exhaust gas purification catalyst have reduced cumulative pore volume in a pore diameter range of 0.1-20 μm compared to a cumulative pore volume in a pore diameter range of 0.1-20 μm of inorganic oxide particles before being coated with the inorganic coating layer. Accordingly, the particles for an exhaust gas purification catalyst have a higher thermal conductivity than the inorganic oxide particles before being coated with the inorganic coating layer.
