Abstract

The invention discloses a high-efficiency production method for an environmentally-friendly air catalyst formaldehyde removing agent. The formaldehyde removing agent is a nitrogen-atom-doped nano-sized titanium dioxide air catalyst; and the formaldehyde removing agent is characterized by comprising the following components in percentages by weight: 0.1-5% of nitrogen-atom-doped nano-sized titaniumdioxide, 0.1-1% of a dispersing agent, 0.1-1% of an adhesive, and the balance of solvent water; and the nitrogen-atom-doped nano-sized titanium dioxide is obtained by performing nitridation on titanium dioxide in a ball milling manner, wherein when ball milling is performed, an abrasive ratio is 10:1 to 1:1, a ball milling speed is 100 r / min to 1000 r / min, and ball milling time is 0.5 to 5 hours.The method disclosed by the invention can quickly, efficiently and permanently purify air, thoroughly eliminate harmful gases such as formaldehyde, benzene, toluene, xylene, ammonia and TVOC, and caninhibit and kill bacteria; the method has a simple production process and low production costs, and the product is non-toxic, odorless, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of air catalyst aldehyde remover, in particular to an efficient and environment-friendly production method of air catalyst aldehyde remover. Background technique [0002] Since Professor Fujishima Akira of Japan first discovered the photocatalytic properties of TiO2 in the 1970s, TiO2 photocatalytic technology has developed rapidly in the fields of solar cell hydrogen production, environmental pollution control, sterilization, and disinfection. Especially in recent years, with the With the increasingly prominent energy and environmental problems worldwide, the research on photocatalytic technology has received more and more attention. [0003] However, the semiconductor band gap of TiO2 is 3.2 electron volts, which determines that TiO2 can only absorb light in the ultraviolet region, and the ultraviolet light in indoor lighting is very weak, and the general TiO2 applied to indoor air purification has little ...
