Embodiment approach
[0036] The present invention provides a kind of preparation method of air purification material, and a kind of specific embodiment comprises the following steps:
[0037] Preparation of manganese catalyst particles;
[0038] Preparation of modified activated carbon particles;
[0039] Mix the manganese-based catalyst particles with the modified activated carbon particles at a mass ratio of 1: (0.25-5).
[0040] The preparation method is simple in operation and easy to implement. The manganese-based catalyst particles in the prepared air purification material are aimed at the decomposition of small molecules such as formaldehyde and acetaldehyde; the modified activated carbon particles are aimed at the removal of macromolecules.
[0041] Manganese-based catalyst particles have a removal rate of 95.8%-98.3% for small molecules such as formaldehyde and acetaldehyde in indoor decoration pollution gases, and can decompose formaldehyde and acetaldehyde into harmless substances at ...
