The invention discloses a nano Co3O4 supported catalyst for catalytic oxidation of VOCs in biomass boiler flue gas and a preparation method thereof. The nano Co3O4 supported catalyst comprises a carrier and a catalyst supported on the carrier. Active component, the carrier is nano Co 3 O 4 , which is assembled from small-sized Co 3 O 4 nano-sheets; the size of the small-sized Co 3 O 4 nano-sheets is 1-20 nm; the active component One or more selected from oxides of copper, iron, chromium, tin or manganese. The nano-Co 3 O 4 supported catalyst disclosed by the invention has novel microscopic appearance, and when used in the catalytic oxidation reaction of VOCs in biomass boiler flue gas, the catalyst has high low-temperature activity of the catalyst and is resistant to poisoning in a complex environment where various toxic substances coexist Features of excellent performance. |
