The invention provides a preparation method of a
manganese-based composite
metal oxide ozonolysis catalyst, and belongs to the fields of
catalysis and
environmental protection. The method uses a redoxprecipitation process to synthesize the nano-fibrous
manganese-based composite
transition metal oxide catalyst. The preparation method of the catalyst has the advantages of simple process, mild conditions, and realization of high stability of catalytic
ozonolysis. The catalyst prepared by the method disclosed in the invention has a
high ozone removal
catalysis activity, and can realize complete removal of
ozone at normal temperature.
