Can photocatalysts really remove formaldehyde?

The technology of indoor environmental treatment (that is, formaldehyde removal) recognized and recommended by the state is "photocatalytic comprehensive treatment technology", please check the official website of the Ministry of Environmental Protection and the Ministry of Commerce for details, and the core product of "photocatalytic comprehensive treatment technology" is "photocatalyst".

Photocatalyst is widely used in Japan, and the technology is relatively mature, and the most authoritative association in Japan in the photocatalyst industry is PIAJ Photocatalyst Industry Co., Ltd., which has 94 members, including Toto, Toshiba, Ishihara, Taiyo and other group companies that are more famous in China.

The effect of photocatalyst in removing formaldehyde is definitely the most effective and thorough, but the premise is that the photocatalyst you use must be a real photocatalyst, and the invalidity theory of photocatalyst is mostly from the remarks of many users who have used fake and shoddy products.

A good photocatalyst must be effective, and it is not necessarily effective as long as it is a product imported from Japan, it is the same in any country, there are counterfeiting companies, even if it is a good brand, there are many A goods, so if you want to buy a good way, you can only master the method of choosing products yourself.

The Japan Photocatalyst Association has a standard for judging the quality of photocatalyst products, referred to as PIAJ certification, one of the methods is fading reaction, in fact, this method is very simple, you can do similar experiments at home, and as long as a formaldehyde test box can judge whether the formaldehyde removal products you buy are true and effective.

Is it useful for photocatalysts to remove formaldehyde? Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nanoscale and titanium dioxide, and is one of the safest materials for controlling indoor environmental pollution in the world.

Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nanoscale titanium dioxide, which is coated on the surface of the substrate and produces a strong catalytic degradation function under the action of ultraviolet light and visible light: it can effectively degrade toxic and harmful gases in the air; It can effectively kill a variety of bacteria, and can decompose and harmless the toxins released by bacteria or fungi; At the same time, it also has the functions of formaldehyde removal, deodorization, anti-fouling, and air purification.

It is useful, but the quality of photocatalyst products on the market is different. When buying, take a look at the ingredient list, but additives with too many chemicals may be harmful to the human body, in addition to formaldehyde, it is recommended that you buy some friends around you, because the photocatalysts on the market are mixed, and the products are also mixed. You better see how the effect is, remember to ventilate it often.

Or try a photophyll formaldehyde removal material I used before, this is an upgrade of photocatalyst and is pure plant extraction, the taste is fresh and harmless.
