CATALYST FOR CLEANING EXHAUST GAS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To enhance the heat resistance of a catalyst for cleaning an exhaust gas, which keeps hollow complex oxide particles containing Ce and Zr included in a catalyst layer on a carrier. <P>SOLUTION: The mass ratio of CeO<SB>2</SB>/ZrO<SB>2</SB>of the Ce-Zr based hollow complex oxide particles is made 50/50 or more and also the mass ratio of a cubic crystal in the hollow complex oxide particles is made 74-82%. <P>COPYRIGHT: (C)2008,JPO&INPIT |
