Catalyst for removing indoor formaldehyde and preparation method thereof

The invention relates to the chemical field, and particularly relates to a catalyst for removing indoor formaldehyde and a preparation method thereof. The catalyst comprises, by weight, 35 to 45 parts of nano titanium dioxide, 6 to 10 parts of octaphenyl polyoxyethyiene, 6 to 10 parts of benzene, 4 to 8 parts of hydrogen peroxide, 4 to 5 parts of dimercaprol, 2 to 3 parts of DTPMP, 0.5 to 1 part of malonic acid, 0.5 to 1 part of aluminium chloride and the balancing being pure water. The catalyst quickly penetrates into the plate after being sprayed directly on the plate surface, the adhesive force is strong, and under the effects of the catalysis of titanium dioxide and other auxiliaries, the catalyst is capable of rapidly and effectively degrading indoor noxious substances including formaldehyde, benzene, toluene, dimethylbenzene, ammonia and total volatile organic compounds(TVOC). The catalyst has the advantages of low cost, strong adhesive force, good catalyst activity and long efficacy. 本发明涉及化工领域，特别是涉及种用于
