Description

Photocatalytic optical fiber fabric with harmful gas degradation function and preparation method thereof
Technical Field
The invention belongs to the field of harmful gas degradation, and particularly relates to a photocatalytic optical fiber fabric with a harmful gas degradation function and a preparation method thereof.
Background
The quality of indoor air is directly related to human health. Volatile Organic Compounds (VOCs) have become the main source of indoor pollution due to their characteristics of high volatility, high toxicity, strong irritation and the like, wherein the VOCs such as formaldehyde and benzene series (benzene, toluene, xylene and the like) are classified as class I carcinogens by the international cancer research organization. The furniture board, the paint coating and the textile slowly release gases such as formaldehyde, benzene, toluene and the like in the long-term use process. Indoor formaldehyde and benzene series with higher concentration can not only destroy organs such as central nervous system, liver, spleen and lung of people, but also can cause diseases such as bronchial asthma, lung cancer, leukemia and the like, and even cause death in serious conditions. Therefore, the method has very important research significance for treating harmful gases such as formaldehyde, benzene series and the like in indoor air.
The treatment technology of formaldehyde, benzene series and other harmful gases mainly comprises an adsorption method, a low-temperature plasma technology, a microbial filtration method, a photocatalysis technology and the like. Among them, the photocatalytic technology is gradually attracting attention due to its advantages of easy operation and low cost. The photocatalytic degradation is to take a semiconductor material as a reaction catalyst, generate high-activity oxidation substances under the action of a light medium, react with harmful pollutants, and finally convert the high-activity oxidation substances into products harmless to the environment, so that the aim of degrading pollution is fulfilled. At present, many photocatalytic materials for removing formaldehyde and benzene series degradation in air have been reported in the literature, but these materials have the following problems: (1) the photocatalyst is directly used in the form of powder or particles, is easy to blow away by wind, is inconvenient to carry and store, and has small contact area with harmful gas, so that the photocatalytic degradation efficiency is directly influenced; (2) the photocatalyst can play a role of photocatalysis only under the irradiation of strong light of an external light source, so the photocatalyst cannot be applied in dark environment (cloudy day and night); (3) the photocatalyst can only catalyze and degrade a certain harmful gas at a time, and indoor air usually contains a plurality of harmful gases, so that the actual requirements cannot be met.
