Background

With the increasing living standard and health consciousness of people, the problem of air pollution gradually emerges. One of the most immediate highlights is the reduced tolerance for air odors.

The odor pollutant is a kind of perception (smell) pollution which is perceived by the fact that the odor in the substances such as atmosphere, water, waste and the like acts on the olfactory thinking of people through air media. Any gaseous substance that can produce an offensive odor that is harmful to the human living environment and intolerable, and that causes it to have an unpleasant sensation, is commonly referred to as an offensive odor pollutant. The malodorous pollutants are of various types, some of which are harmful to human beings, such as thiols, ammonia, hydrogen sulfide, dimethyl disulfide, trimethylamine, formaldehyde, styrene, and the like. The malodorous pollutants can affect the respiration, digestion, cardiovascular, endocrine and nervous systems of human bodies, and the high-concentration malodorous gas can even suffocate and die people, thereby causing great harm to the health of human beings. In addition, the malodors also affect human social life, for example, due to the influence of malodorous substances, the normal production and life of people are disturbed, the working efficiency is reduced, and the life quality is reduced.

Currently, the mainstream odor elimination products on the market include: firstly, essence air fresheners, such as household volatile liquid, air refreshing spray and the like, have the function of covering up odor by releasing fragrance molecules, do not achieve the aim of air purification substantially, but increase the content of total volatile matters in the air; secondly, the adsorption deodorant, such as activated carbon adsorbent, is used for adsorbing odor molecules by utilizing the adsorption effect of the deodorant, but the deodorant needs desorption treatment after the adsorption capacity is saturated, and secondary pollution is easily caused in the desorption process.
