| titleOfInvention | Copper-based cerium-cobalt-lanthanum composite oxide catalyst and preparation method thereof |
| abstract | The invention discloses a catalyst for selective reduction of NO by propylene and a preparation method thereof. The catalyst is low in optimal catalytic activity temperature and has high catalytic activity in a wide temperature range. The preparation method comprises the following steps: regulating the pH value of a (NH4)2CO3 or NH4HCO3 solution to 8-12 with ammonia water, heating, and slowly and dropwisely adding a mixed salt solution of cerium salt, cobalt salt and lanthanum salt while stirring; drying the generated solid, and roasting to obtain a Ce-Co-La-O composite oxide supporter; and impregnating the obtained Ce-Co-La-O composite oxide supporter in a copper salt water solution, and roasting to obtain the Cu/Ce-Co-La-O oxide. |
