Photocatalyst type formaldehyde scavenger and preparation method thereof

The invention provides a photocatalyst type formaldehyde scavenger to solve the problems that in the prior art, the formaldehyde removing rate is low, secondary pollution is prone to being caused, and the cost is high. The photocatalyst type formaldehyde scavenger is composed of 1%-10% of a nano silver paste solution, 1%-15% of photocatalyst, 0%-5% of an N-lauroyl-L-glutamic acid surfactant, 0%-5% of polyethylene glycol, 1%-8% of a formaldehyde trapping agent, and the balance deionized water. The photocatalyst can be an anatase nanometer titania colloidal solution. The obtained photocatalyst type formaldehyde scavenger has the advantages of being high in formaldehyde removing rate, free of secondary pollution, environmentally friendly, economical and practical, and meanwhile, the photocatalyst type formaldehyde scavenger can be used for scavenging volatile organic compounds such as benzene, methylbenzene and xylene. 本发明针对现有技术中甲醛去除率均较低、易引起二次污染、成本较高的问题，提供了种光触媒型甲醛清除剂，由以下组分构成：1%~10%的纳米银浆溶液，1%~15%的光触媒，0%~5%月桂酰基谷氨酸
