Titanium building materials with titanium dioxide nanotube array structure have the functions of gas purification and sewage degradation. It plays a strong role in alleviating haze (PM2.5, PM10), degrading formaldehyde (CH2O) and other harmful gases in the air, reducing greenhouse gases carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCS), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6).

After using titanium (photocatalytic) material, the air quality in the tunnel is improved to a certain extent. The average reduction of pollutant NO2 is 34.5%, the average reduction of CO is 39.2%, and the average reduction of no is 5.7%. For streets paved with TiO2, the pollutants can be reduced by about 45% under ideal weather conditions and generally by about 19% under natural conditions.

When used in the exterior wall of a building, the titanium oxide on the surface of the titanium plate reacts with the water and oxygen in the air by using the photocatalyst technology to generate two kinds of active oxygen with strong decomposition power. This kind of active oxygen can effectively oxidize the nitrogen oxides of the air pollutants. 100 ㎡ is equivalent to the purification capacity of 27 tennis courts, and can remove the nitrogen oxides emitted from the exhaust of about 80 ordinary cars.

Excellent durability:

Metal titanium has good corrosion resistance. It can withstand the corrosive environment such as marine environment, industrial radiation, acid rain, urban pollution, volcanic ash, etc., and is especially suitable for use as the roof and wall of buildings. Titanium material is more resistant to urban pollution, industrial radiation and extreme corrosive atmospheric conditions than stainless steel and aluminum. It will not be weathered and faded due to ultraviolet irradiation. It is resistant to acid rain corrosion, can resist stress, and can resist contact corrosion, pitting and crevice corrosion with different substances.

With dazzling color attribute:

Titanium has the property of being easily colored. After the titanium plate is anodized, a transparent oxide film with a thickness of several hundred nanometers to several thousand nanometers will be formed on the surface. Due to the interference of light, the color will appear. According to the thickness of the oxide film, the unique color that is difficult to obtain for aluminum and stainless steel will appear.

Environmental protection materials:

Titanium can be recycled 100% by remelting, and will not decompose and emit harmful substances, so it will not pollute the environment. While other metals exposed to pollutants will be eroded or corroded, leaking metal ions and entering groundwater, causing environmental problems. Titanium complies with the "green environmental protection building product specification".
