Natural mineral material and application thereof in formaldehyde adsorption and decomposition and air purification

The invention relates to a natural mineral material and application thereof in formaldehyde adsorption and decomposition and air purification, and belongs to the technical field of chemical catalytic decomposition. The natural mineral material is manganese-containing potassium ore powder, the manganese content is 40-55wt%, and the granularity of the manganese-containing potassium ore powder is 60-200 meshes; and the manganese ore is obtained by crushing and reselecting natural manganese ore. The natural mineral material can be applied to formaldehyde adsorption and decomposition and air purification. Natural inorganic minerals are mainly utilized to effectively, continuously and quickly adsorb and decompose formaldehyde pollution in indoor air; the process is simple, the cost is low, formaldehyde and other volatile organic compounds (TVOC) can be efficiently removed, and the contained components are non-toxic and environment-friendly; and the material can be widely applied to indoor environments such as famil
