Abstract

The invention discloses a nanometer photocatalyst emulsion containing zinc oxide and a preparation method thereof, wherein the nanometer photocatalyst emulsion is prepared from the following raw materials in parts by weight: 2 to 8 parts of butyl titanate, 4 to 16 parts of nanometer silicon dioxide, 2 to 4 parts of zinc acetate, 0.35 to 0.7 part of cupric nitrate, 0.15 to 0.3 part of cerous nitrate, 0.15 to 0.3 part of selenium nitrate, 50 to 100 parts of organic mixed solutions, 400 to 600 parts of triethylene glycol and 10 to 30 parts of water; the nanometer silicon dioxide is used; the support and carrier effects can be provided for nanometer titanium dioxide, nanometer zinc and metal catalysts; the catalysis effect of the photocatalyst is greatly improved; the bonding effect is improved; antibacterial ions can be adsorbed to achieve the sterilization and antibacterial effects. The nanometer photocatalyst emulsion can be used for treating various organic molecules with foreign smell; the preparation method is simple; the stability is high; the adsorption rate is high; two kinds of different use methods can be used; the use range is wide; a very good treatment effect can be achieved on various articles with foreign smell.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a novel air purifier and a preparation method thereof, in particular to a zinc oxide-containing nano photocatalyst emulsion and a preparation method thereof. Background technique [0002] At present, air purifiers are divided into two types, one is the air purifier that uses its own fragrance to cover up the odor, and the other is the air purifier that uses adsorption or chemical reaction to absorb or degrade harmful gases. The first one is just to cover up the odor, and does not remove the harmful gas itself; and the second one is currently divided into two types in the market, one is the traditional adsorption principle of activated carbon for adsorption. This method only absorbs the harmful gas, but does not completely remove it. The adsorbent needs to be replaced after the adsorption is saturated; the other is a new type of photocatalyst. Under light irradiation, the v...
