H ₂ O + h ⁺ → OH + H

As such, when ultraviolet rays are irradiated onto a surface of an object coated with titanium dioxide (TiO ₂ ), electrons are transferred to a conduction band to form electrons and holes. Since these electrons and holes have very strong oxidizing and reducing power, they react with water vapor (H ₂ O) or oxygen (O ₂ ) in the air to generate strong OH radicals, H radicals, and the like. And oxidize and decompose all organic matter or pollutants contained in the air.

Therefore, the photocatalyst of titanium dioxide (TiO ₂ ) is organic compounds and contaminants contained in the air are nitrogen compounds, hydrocarbons, carbon monoxide, sulfur oxides, ozone, and the like, formaldehyde, toluene, xylene, benzene, radon and the like, tobacco, tobacco Purifies the air by oxidizing and decomposing odors such as smoke, odors and other ammonia, and kills harmful organisms such as house dust mites, bacteria, viruses, molds, and bacteria, and protects eyesight by blocking UV rays such as lighting. At the same time, it also has the effect of promoting the growth of living things, such as the effect of sunshine.
