Abstract
The invention discloses preparation of a cobalt-load cerium manganese oxide catalyst. Cerium manganese oxide is prepared through an oxidization reduction method, then cobalt is loaded to the cerium manganese oxide through an equivalent-volume impregnation method, manganese oxide has good oxidization performance, cerium oxide has excellent oxygen storage and release capacity, cobalt oxide also has certain oxidization performance, the catalyst has good purifying efficiency on low-concentration nitric oxide, the conversation rate can be 96% at the temperature of 25 DEG C, long service life can also be kept, meanwhile raw materials for preparing the catalyst are easy to obtain, the technology is simple, cost is low, and industrial production can be achieved easily.
