Preparation method of catalytic material for degrading formaldehyde and prepared catalytic material and application thereof

The invention belongs to the technical field of new materials, and discloses a preparation method of a catalytic material for degrading formaldehyde, the preparation method comprises the following steps: (1) adding a mesoporous molecular sieve into a manganous nitrate solution, uniformly stirring and mixing to obtain a mixed solution, adding a pH regulator into the mixed solution, and regulating the pH of the mixed solution to be alkaline; adding a tungsten hexachloride solution into the mixed solution, stirring for reaction, standing after reaction, and collecting a precipitate after standing; and (2) washing and drying the precipitate prepared in the step (1), and calcining at 400-500 DEG C for 3-6 hours to obtain the catalytic material. According to the preparation method of the catalytic material for degrading the formaldehyde, the manganese oxide and the metal tungsten can be loaded on the mesoporous molecular sieve, the manganese oxide and the tungsten can generate a synergistic effect to catalyze the f
