Abstract

The invention relates to the technical field of photocatalyst spray, and discloses photocatalyst spray for air purification, which is prepared from the following raw materials in parts by weight: 1 to10 parts of I-TiO2, 1 to 5 parts of nano titanium dioxide, 5 to 15 parts of polyethylene glycol, 5 to 20 parts of glycerol, 1 to 5 parts of tourmaline powder, 5 to 10 parts of nano silicon dioxide and 1 to 8 parts of nano silver. According to the photocatalyst spray, effects of the spray after iodine doping is superior to that of a pure TiO2 photocatalyst; the main reason is that on one hand, a new energy level can be introduced into a TiO2 energy band gap by an iodine element so that the band gap width of TiO2 is reduced and TiO2 surface properties and effects of enhancing photo-induced electron hole pair separation are achieved; on the other hand, impurity replacement is carried out after iodine enters TiO2 crystal lattices, so that oxygen vacancies and defects of photo-induced electroncenters capable of generating strong-oxidation active particles on the surface of TiO2 are increased, and the active effect of the photocatalyst is enhanced.

Description

technical field [0001] The invention relates to the technical field of photocatalyst spray, in particular to an air-purifying photocatalyst spray. Background technique [0002] At present, PM2.5 pollution is an environmental problem that cannot be ignored in our country. Even when the doors and windows are closed, it can slowly penetrate into the room. Titanium dioxide purification technology has received great attention due to its advantages of environmental protection, high efficiency, and thorough purification. [0003] However, TiO 2 It can only produce photocatalyst activity after absorbing a certain amount of ultraviolet energy, which will make it unable to make full use of the visible light energy in sunlight. In addition, the glass material of the indoor window also absorbs ultraviolet light, making it indoors. when TiO 2 The ultraviolet light that can be absorbed is more limited, which causes TiO 2 The limitations of purifying indoor air.
