Shijiazhuang explain photocatalyst technology companies in addition to formaldehyde reaction principle

Shijiazhuang addition to formaldehyde companies - Shijiazhuang Environmental Protection Engineering Co., better than good, a senior environmental control division Zhang Gong explain photocatalyst technology reaction principle: photocatalyst [Photocatalyst] light [Photo = Light] + catalyst (catalyst) [catalyst] compound words. Photocatalyst is a kind of nanoscale titanium dioxide represented photocatalytic functional optical semiconductor material in general. Environmental experts internationally known as the "21st century high-tech environmental purification materials," it is widely used in indoor air pollution and beautify the city, clean up air pollution and prevent various environmental areas within the hospital cross-infection. Titania photocatalyst titanium feedstock for the crust element fourth largest element. Titanium dioxide (TiO2) that is one form of existence of its oxide, TiO2 itself N-type semiconductor, TiO2 anatase (A-type), rutile (R-type) and brookite (B-type) in nature three kinds of crystal forms exist, the most widely used is the A-type and B-type. When they are used alone or in a mixture of both, as industrial pigments (titanium dioxide), food additives (with the US FDA Food Inspection and Certification Center), cosmetics (UV absorber), etc. are widely used. Anatase titanium dioxide photocatalyst, it is but natural light after absorbing ultraviolet light, the photosynthesis of plants to produce a similar principle, which is the nature of light energy is converted into the desired chemical reaction "activation energy" to act as a catalyst. After TiO2 reaction by light itself will produce a set of each hole and the positively and negatively charged electrons, holes having a strong oxidation, electrons have a super reducing ability. By reaction with water vapor in the TiO2 film on the surface, the formation of negative oxygen ions and reactive oxygen species, hydroxyl radicals, which are highly oxidative free radicals can break down almost all of the human body and environmentally harmful organic substances and some inorganic thereof. And has a powerful antibacterial, deodorant, oil decomposition, mildew, algae and air purification and other effects, for example: it can destroy the cell membrane of cells, the bacteria mass loss to death; can decompose harmful gases such as formaldehyde, ammonia, benzene, etc. , to convert it into harmless water, carbon dioxide and salt, so as to purify the environment, clean air effect.
