废气净化用催化剂及其制造方法以及使用其的废气净化方法

Catalyst for exhaust gas purification, method for producing the same, and exhaust gas purification method using the same
Abstract:
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.
Abstract(Chinese):

本发明的目的是提供一种排气净化用催化剂，其能够在低温下有效地处理排气中的废气，特别是一氧化碳（CO）和烃（HC） 生产废气净化催化剂。 其目的是通过具有含有Al 2 O 3的载体和选自氧化锆（ZrO 2），氧化铈（CeO 2），氧化钇（Y 2 O 3）等的一种以上的金属氧化物而得到的废气净化用催化剂实现。 ），氧化钕（Nd 2 O 3），氧化硅（SiO 2）和氧化钛（TiO 2）支持一种或多种选自金（Au），银（Ag），铂（Pt），钯（Pd） ，铑（Rh），铱（Ir），钌（Ru）和锇（Os）。 金属氧化物的粒径小于10nm。
