Self-assembled honeycomb activated carbon-nanoparticle module and preparation method thereof

Abstract

The invention provides a self-assembled honeycomb activated carbon-nanoparticle module and a preparation method thereof. The self-assembled honeycomb activated carbon-nanoparticle module comprises a carrier, an adsorbent, a curing agent and nanoparticles, the carrier, the adsorbent, the curing agent and the nanoparticles are laminated and assembled, and the nanoparticles cover the surface of the carrier. According to the self-assembled honeycomb activated carbon-nanoparticle module, the preparation method is simple, the honeycomb activated carbon provides an extremely high specific surface area, nanoparticles are uniformly self-assembled on the surface of the honeycomb activated carbon, and the purpose of thoroughly adsorbing and decomposing formaldehyde, acetaldehyde, benzene, methylbenzene, xylene, VOCs and other harmful chemical substances in air is achieved.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a self-assembled honeycomb activated carbon-nano particle module and a preparation method thereof. Background technique [0002] With the development and progress of society, the problem of chemical pollution indoors and in cars has attracted more and more attention. Formaldehyde, benzene series, ammonia, volatile organic compounds (VOCs) and other polluting gases are the main chemical substances that cause indoor and car pollution, and seriously threaten human health. [0003] At present, the commonly used methods to control indoor and in-vehicle chemical pollution problems are mainly physical methods, chemical methods and methods combining physical and chemical methods. The physical method refers to the use of porous materials such as activated carbon and molecular sieves to adsorb chemical substances such as formaldehyde, benzene series, ammonia, and VOCs in the ai...

AI Technical Summary

Problems solved by technology

The physical method refers to the use of porous materials such as activated carbon and molecular sieves to adsorb chemical substances such as formaldehyde, benzene series, ammonia, and VOCs in the air. This method has a good adsorption effect in a short period of time, but it is prone to adsorption saturation when used for a long time. The final desorption problem makes formaldehyde, benzene series, ammonia, VOCs and other chemical substances volatilize into the air again; chemical method refers to the use of chemical decomposition to remove formaldehyde, benzene series, ammonia, VOCs and other chemical substances in the air However, it is easy to have the problem of low efficiency; the physical and chemical combination method refers to the active adsorption of formaldehyde, benzene series, ammonia, VOCs and other chemical substances in the air through the combination of the two, and then further decomposes and removes them, such as activated carbon - Titanium dioxide material, however, most of this material has the problem that titanium dioxide is not firmly supported on activated carbon, which seriously affects its actual production and application
