Air purification
Titanium dioxide, as a photocatalyst coating pigment, not only is a kind of environmental safety of cleaning agent, but also to save energy and Protect environment resources function.
Scientists early in Japan and the UK will of titanium dioxide coated in city road paving stone surface, for cleaning surface air. Titanium dioxide can be mixed with asphalt, reduce the pollutants in the air. When a vehicle passes, titanium dioxide containing concrete or asphalt can purify the air, eliminate vehicle emissions in 25% to 45% of the nitrogen oxides. The titanium oxide coating on the surface of concrete, the air cleaning effect equally significant.
To cool the earth
In 2012 May, British scientists have proposed a bold vision, they think through the stratosphere spraying enough TiO2 to reflect sunlight, so as to achieve the purpose of cooling the earth, doing so can effectively offset caused by global warming a variety of adverse climatic factors.
The titanium dioxide can effectively reflect the sun's light reflection, and its property is stable, has good covering power, if long-term spray can play a role in the stratosphere. British scientists have proposed, can use the high altitude balloon this chemical substances into the stratosphere, then release, once the titanium dioxide is evenly distributed in the earth's stratosphere, can effectively reflect the light of the sun, so as to cool the earth.
President of consulting company in the United Kingdom, chemical engineering science and technology Davidson's scientist Peter Davidson is in charge of this project, he said, just need to ship 3000000 tons of titanium dioxide into the earth's stratosphere, can form a protective layer thickness of 1 mm in the earth's stratosphere, the greenhouse effect and it can play a role is huge - enough to offset two times current levels of carbon dioxide in the atmosphere resulting.
