▎ 摘　　要

NOVELTY - Nano photo-catalyst formaldehyde scavenging agent comprises nano photocatalyst, dispersant, formaldehyde inducer, penetrating agent, graphene oxide and deionized water. USE - Nano photo-catalyst formaldehyde scavenging agent used for removing formaldehyde from air. The formaldehyde is carcinogenic and malformation substance, which is absorbed by respiratory tract immune system and biological macromolecule to cause the organism to be damaged ADVANTAGE - The nano photo-catalyst formaldehyde scavenging agent has a formaldehyde removing rate of more than 90%, and continuously absorb and decompose harmful gas to achieve the effect of purifying air, and ensures long-acting effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the nano-photocatalyst formaldehyde scavenger, which involves: pouring the deionized water and the dispersing agent into a stirring device, and stirring and mixing for 30-40 minutes at the stirring speed of 1000-1200 revolution per minute; adding the nano photocatalyst and the graphene oxide into the solution, and continuing stirring until the nano photocatalyst and the graphene oxide are completely mixed; finally adding a formaldehyde inducer and a penetrant into the solution, heating and stirring by using a stirring device, controlling the heating temperature at 30-35℃, where stirring time is 2-3.5 hours, controlling the stirring speed at 600-1200 revolution per minute, and cooling to room temperature after stirring is finished.
