Embodiment 1

[0021] 1) Mn-doped TiO 2 Preparation: Dissolve 8.5mL of butyl titanate in 20mL of absolute ethanol, and disperse it ultrasonically for 10 minutes to obtain solution A; mix 10mL of absolute ethanol and 10mL of distilled water, adjust the pH value to 3 with concentrated HCl, and then dissolve 10ml of The manganese chloride saturated solution was dissolved in it, ultrasonically dispersed for 10 minutes to obtain solution B, solution A was slowly dropped into solution B under magnetic stirring, and stirring was continued for 1 hour after the titration was completed to obtain a translucent, light yellow sol. Aged in air for 48 hours to obtain TiO 2 gel. Put the gel into a constant temperature water bath at 80°C, and volatilize the water and organic solvent in the gel under the action of a mechanical stirrer to obtain a white dry gel. Grind the xerogel into powder and put it into a tube furnace, bake it at 500°C for 3 hours, then cool it naturally and take it out for grinding.

Abstract

The invention provides a Mn-loaded TiO2-doped activated carbon fiber air purifier filtering net, which comprises the following materials in parts by weight: 8-10 parts of bentonite, 5-8 parts of Mn-doped TiO2, 20-22 parts of activated carbon powder, 0.5-1 parts of nano-silver, 15-20 parts of epoxy resin crosslinker, and 60-75 parts of activated carbon fiber. In the filtering net disclosed by the invention, Mn is doped into titanium oxide to improve photon utilization rate during reaction, Mn-doped TiO2 and other material are together loaded on activated carbon fiber, and the adsorptive action of the porous structure of the activated carbon fiber is utilized to enhance the air purification effect.

Description

technical field [0001] The invention belongs to the technical field of air purification materials, and in particular relates to a loaded Mn-doped TiO 2 Activated carbon fiber air purifier filter screen and preparation method. Background technique [0002] Activated carbon fiber is a new type of adsorption functional material developed on the basis of carbon fiber in the early 1970s. It is the third generation of activated carbon adsorption material after powdery and granular activated carbon. Activated carbon fiber has fine fiber diameter, well-developed micropore structure, large specific surface area and adsorption capacity, and a large number of micropores open on the surface of the fiber filament, so the absorption and desorption speed is fast, the pore size distribution is concentrated, and the adsorption capacity for low-concentration adsorbate is special. Excellent and other characteristics, has been widely used in gas purification and wastewater treatment. [0003]...
