The invention discloses a catalyst for catalytically degrading ethylene, a ripening agent in fruits and vegetables at room temperature, and its preparation and application. The method is as follows: dissolving the bismuth-containing compound in nitric acid, adding the nitric acid solution containing the bismuth compound dropwise to the alkaline MnO 2 solution and mixing evenly, reacting at 30-60 DEG C for 2-4 hours, aging, centrifuging, Wash to neutrality and dry to obtain Bi-Mn bimetallic oxide catalyst. The preparation method of the invention is simple, the doping element can be efficiently loaded, and the obtained catalyst realizes the efficient catalytic degradation of ethylene under normal temperature conditions. |
