Problems solved by technology

In the field of air treatment, since the surface micropore size of activated carbon is 50-100 times smaller than that of microporous ceramic balls, that is to say, the surface specific area of ​​activated carbon is 50-100 times larger than that of microporous ceramic balls, so activated carbon The surface area of ​​microporous ceramic balls is larger and the adsorption capacity is stronger. At the same time, the price of microporous ceramic balls is 5 to 10 times higher than that of activated carbon, and the economy is not as good as that of activated carbon. Therefore, the application of microporous ceramic particles in the field of air treatment is not widely used at this stage.
[0004] However, it is precisely because the surface micropore size of activated carbon is too small that it is difficult to load other air purification molecules, and it can only play the role of surface adsorption. The adsorption capacity is limited, and the effect of practical application is not ideal.
Therefore, whether it is possible to combine the characteristics of large micropore size of microporous ceramic particles with other air purification molecules to overcome the defects that traditional activated carbon can only play the role of surface adsorption and limited adsorption capacity when used alone, and greatly improve air quality. What about the effect of purification? This is a topic worthy of research at present

Abstract

The invention provides an air purification material and its preparation method and application, and relates to the technical field of purification materials. The air purification material is microporous ceramic particles with purification molecules attached to pores; the purification molecules include redox degradation molecules. The redox degradation molecule is titanium dioxide phosphate. The present invention uses microporous ceramic particles as a carrier in combination with titanium dioxide phosphate to overcome the technical shortcomings of the two alone, improves the reaction rate, and achieves a more ideal pollutant removal effect. At the same time, during the working process of the air purification material of the present invention, It does not produce harmful substances to the human body, nor consumes oxygen in the air, etc., wraps and settles harmful substances in the air, and finally decomposes into atmospheric components such as water, carbon dioxide, and nitride.

Description

technical field [0001] The invention relates to the technical field of purification materials, in particular to an air purification material and its preparation method and application. Background technique [0002] Indoor air pollution refers to the indoor air pollution caused by various reasons in residences, schools, offices, shopping malls, hotels, various restaurants, cafes, bars, public buildings, and various public gathering places due to human activities. Hazardous substances exceed the standard, thereby affecting the indoor environmental pollution behavior of human health. The harmful substances include formaldehyde, benzene series, ammonia, TVOC, etc. With the intensification of the pollution of these harmful substances, the human body will produce sub-health reactions and even threaten life safety. Therefore, in recent years, indoor air pollution has been paid more and more attention by people. [0003] Microporous ceramic particles contain a large number of open...
