Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a high-efficiency air purification photocatalyst filter net and a preparation method thereof. Background technique [0002] People spend more than 80% of their time indoors and in cars. However, the concentration of volatile pollutants such as toluene, benzene, and formaldehyde in indoors or cars is getting higher and higher. Various volatile pollutants will seriously affect people's health. Health, these have led to people paying more and more attention to air purification products. [0003] Common air purification products are mainly divided into the following categories: activated carbon adsorption, photocatalyst degradation, electrostatic adsorption, ultraviolet irradiation, negative ion technology and ozone technology, etc., among which electrostatic adsorption is expensive, complex in structure and produces a certain concentration of Ozone is harmful to the human ...
