摘要:
The purpose of the present invention is to provide a catalyst for exhaust gas purification, which is capable of effectively processing an exhaust gas, particularly carbon monoxide (CO) and hydrocarbon (HC) in the exhaust gas at a low temperature, and a method for producing the catalyst for exhaust gas purification. The purpose is achieved by a catalyst for exhaust gas purification, which is obtained by having a carrier that contains Al2O3 and one or more metal oxides selected from the group consisting of zirconium oxide (ZrO2), cerium oxide (CeO2), yttrium oxide (Y2O3), neodymium oxide (Nd2O3), silicon oxide (SiO2) and titanium oxide (TiO2) support one or more catalyst components selected from the group consisting of gold (Au), silver (Ag), platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), ruthenium (Ru) and osmium (Os). The metal oxides have particle diameters of less than 10 nm.
