Carbon-based catalytic purification material for efficiently adsorbing and decomposing harmful substances and application of material

Abstract

The invention belongs to the technical field of air purification, and particularly relates to a carbon-based catalytic purification material for efficiently adsorbing and decomposing harmful substances and application of the carbon-based catalytic purification material, aiming to solve the technical problem that the air purification effect is poor in the prior art. The catalytic purification material comprises a carbon-based carrier, wherein the carbon-based carrier is loaded into any one or the combination of phosphate titanium dioxide and tetrapod-like zinc oxide whiskers. According to the invention, the excellent catalytic property of phosphate titanium dioxide and tetrapod-like zinc oxide whiskers and the powerful adsorption performance of the activated carbon are combined; substances including formaldehyde, benzene and the like are saved, catalytic reaction can be naturally carried out as long as water and oxygen exist in air, without needing of irradiation of visible light and ultraviolet rays, and the catalytic purification material can be conveniently used in various occasions, and also can be prepared into products such as products with various shapes and various functions, such as air filtering materials, air purification bags, air purification sheets, air purification boxes and air purification modules.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a carbon-based catalytic purification material for efficiently adsorbing and decomposing harmful substances and its application. Background technique [0002] With the continuous heating up of interior decoration and the wide application of various building materials, the resulting indoor air pollution has attracted more and more attention. Among them, the main pollutants are from paint, plywood, particle board, interior wall paint, plastic Formaldehyde, benzene, VOCs (Volatile Organic Compounds) and other volatile organic compounds in veneers and other materials. According to the survey results, more than 70% of the surveyed model households have varying degrees of excessive indoor air pollution. According to the national standard for indoor air evaluation, 75% of the samples exceeded the standard. The top four harmful substances in pollution are formaldeh...

Problems solved by technology

[0004] However, ordinary activated carbon has at least the following disadvantages: 1. It can only adsorb harmful substances. When used for a period of time, it will lead to adsorption saturation, loss of purification ability, and short service life.

2. Activated carbon with saturated adsorption will lead to desorption and overflow of harmful substances. Long-term storage will not only fail to purify, but will become a source of pollution. Although the adsorption capacity can be improved again by exposure to the sun, the improvement is limited and the operation is not convenient enough.

[0005] Although the above scheme can realize the regeneration of activated carbon, there are still technical problems such as complex operation process, high cost, large energy consumption, and easy environmental pollution.
