Photocatalyst indoor formaldehyde removal black Technology

Self dispersed nano titanium oxide manufacturers to explain photocatalyst to you.

1、 Photocatalyst has the characteristics of comprehensiveness, sustainability and safety in air purification

Comprehensiveness: photocatalyst can effectively degrade formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other pollutants, and has a wide range of disinfection performance. It can decompose and harmless the toxins released by bacteria or fungi.

Persistence: we know that formaldehyde is a chemical substance, and its release period is as long as 3-15 years. In addition to formaldehyde, many people are concerned about whether it will rebound.

Under the condition of not serious environmental pollution, as long as there is no abrasion and peeling off, the photocatalyst itself will not change and lose. Under the light irradiation, it can continuously purify the pollutants, which has the advantages of lasting time and continuous effect.

Safety: the main raw material of photocatalyst is often used in food and cosmetics in our daily life, so it is non-toxic, harmless, safe and reliable for human body. In the process of air purification, photocatalyst is not directly involved in the chemical reaction, so it will not produce secondary pollution.

2、 There are some conditions for photocatalyst to play a role in purifying air and removing formaldehyde

1. Requirements for light: in order to make the photocatalyst absorb visible light, it is necessary to use the preparation and doping technology of special materials to induce the visible light of photocatalyst, so as to further broaden the light wave absorption range of photocatalyst.

2. Effective concentration: it converts water or oxygen into strong oxidation active groups by absorbing light energy, and strong oxidation active groups degrade air pollutants, so it is necessary to contact water molecules or oxygen molecules directly. The effective contact concentration of photocatalyst is not only related to the concentration of photocatalyst in the solution, but also related to the field process such as spraying tools and spraying methods.

3. Nanoparticle size: it varies according to different photocatalyst materials. In clinical practice, the photocatalyst with nanometer fineness greater than 50nm has no light activity, and it is better to use less than 30nm. The nano size of pure photocatalyst can be about 5 nm.
