A high heat-resistant copper-alumina composite oxide and a method for purifying exhaust gases |
| 摘要 |
<p>A catalyst for reducing NOx in automotive exhaust gases, which is formed of a copper-aluminum composite oxide and which exhibits two peaks in the X-ray spectrum corresponding to interplanar spacings of approximately 0.2 nm and approximately 0.28 nm. This composite oxide exhibits high NOx conversion and superb heat resistance, though its crystal structure is not known yet. <MATH></p> |
