  • Cerium manganese catalyst, preparation method therefor and use thereof
    Patent number: 11684908
    Abstract: A cerium manganese catalyst for ozone decomposition, which is mainly a composite oxide of Mn2O3 and CeO2 with the chemical constitution of CeMnaOx, a being a natural number selected from 6 to 15. A method for preparing a catalyst comprises: mixing a solution containing a cerium source and a manganese source with excessive urea, reacting to obtain a precipitate, washing the precipitate to neutral, drying, and roasting to obtain the cerium manganese catalyst.
    Type: Grant
    Filed: January 16, 2019
    Date of Patent: June 27, 2023
    Assignee: RESEARCH CENTER FOR ECO-ENVIRONMENTAL SCIENCES, CHINESE ACADEMY OF SCIENCES
    Inventors: Hong He, Jinzhu Ma, Xiaotong Li, Changbin Zhang

  • Ce-based composite oxide catalyst, preparation method and application thereof
    Patent number: 9498770
    Abstract: Disclosed is a Ce-based composite oxide catalyst for selective catalytic reducing nitrogen oxides with ammonia, which comprises Ce oxide and at least one oxide of transition metal except Ce. The Ce-based composite oxide catalyst is prepared by a simple method which uses non-toxic and harmless raw materials, and it has the following advantages: high catalytic activity, and excellent selectivity for generating nitrogen etc. The catalyst can be applied in catalytic cleaning plant for nitrogen oxides from mobile and stationary sources.
