Due to the changes in life and work patterns, modern people spend more and more time in the indoor environment, and almost 90 percent of the time is spent indoors. As a result, the poor indoor air quality leads to a large number of “Sick Buildings”, and the number of people suffering from “Architectural Disease Syndrome” is increasing.

The extensive use of new building materials, especially chemical synthetic building materials, has led to the continuous increase of harmful substances in the indoor air, which has led to a serious decline in indoor air quality. The photocatalyst is the general name of photocatalytic photo semiconductor material, which is represented by Nano titanium dioxide. It is one of the safest materials to control indoor environmental pollution in the world.

Photocatalyst can produce photocatalytic reactions similar to photosynthesis and free hydroxyl and reactive oxygen species with strong oxidation capacity under light irradiation, which can oxidize and decompose various organic compounds and some inorganic substances, and destroy the cell membrane of bacteria and solidify the protein of virus, kill bacteria and decompose organic pollutants, as well as decompose organic pollutants into pollution-free water, carbon dioxide and other harmless substances. Therefore, it has a strong function of sterilization, deodorization, anti-mildew, anti-fouling, self-cleaning and purifying air.

Recently, scholars at home and abroad have achieved certain results in photocatalyst treatment of textile and bamboo materials. In fact, photocatalyst has different prospects in the decoration and furniture field with the general improvement of people's living health and environmental protection requirements, and the materials with the function of photocatalyst purification are more and more popular.

Nano tungsten trioxide is an important type N semiconductor. Due to its good optical and electrical properties, it is widely used in lithium-ion batteries, electrochromic devices, gas sensors and photocatalysis, and its popularity is no less than titanium dioxide. For example, some enterprises have used Nano tungsten oxide to prepare a photocatalyst paper-based bamboo curtain in product innovation.

The purification effect of the Nano tungsten oxide photocatalyst paper-based bamboo curtain is 10-20 times that of the existing titanium dioxide photocatalyst, according to the authoritative measurement, and it can produce strong light contact effect under the condition of ordinary visible light. The degradation of formaldehyde can reach more than 70% through the 24-hour room temperature test of white light, black light, and common paper-based bamboo curtain. In a word, its light conversion efficiency is higher, so it can degrade formaldehyde, harmful particles, peculiar smell, and pathogenic bacteria more effectively.
