Problems solved by technology

[0005] Although the above two methods have good disinfection capabilities and show broad application prospects, the above methods have their own problems that are difficult to overcome.
Firstly, the disinfection mechanism is single; secondly, the disinfection speed is slow; finally, the preparation cost is high, these shortcomings seriously limit the promotion and application of the above-

Abstract

The invention relates to a photo-thermal coupling adsorption reaction type sterilization material which is prepared from three layers of organically compounded materials, wherein the outermost layer is a solar photocatalysis sterilization material, the middle layer is an adsorption sterilization material, and the inner layer is a nano metal oxide sterilization material. The percentages of the solar photocatalysis sterilization material, the adsorption sterilization material and the nano metal oxide sterilization material to the total mass of the photo-thermal coupling adsorption reaction type sterilization material are respectively 1-25%, 30-85% and 14-45%. The photo-thermal coupling adsorption reaction type sterilization material is applicable to sterilization of surfaces and internal spaces of person skin, facilities, buildings and the like. The sterilization material is directly in contact with surfaces such as person skin and precise instruments which are contaminated by harmful chemicals.

Description

technical field [0001] The invention relates to the preparation of a photothermal coupling adsorption reaction type disinfection material and the use of the disinfection material to eliminate toxic and dangerous chemicals. Background technique [0002] In recent years, the leakage of toxic and dangerous chemicals (such as pesticides and toxic industrial chemicals) caused by sudden natural disasters and accidents has become one of the major threats to public security; in addition, terrorists may also use Toxic and dangerous chemicals (such as: chemical agents, toxic industrial chemicals, etc.) attack vital departments and people, directly endangering national security. The rapid and efficient disinfection of poisoned personnel, objects and places has become the most important means to ensure the safety of personnel under the above-mentioned forms. [0003] At present, the disinfection methods contaminated with toxic and dangerous chemicals mainly adopt wet method and dry met...
