Nitrogen oxides are the main source of the modern city of atmospheric pollutants, titanium dioxide (TiO2) photosensitive composite materials since the last century since the advent of the mid 90s, with its unique function of atmospheric nitrogen oxide catalytic oxidation into harmless nitrate, commercial application of fast within the eu. About 4% of the proportion of mixed concrete coating technology of photosensitive composite materials, not only has the self-cleaning function, but also more than 80% of the nitrogen oxides up to absorb the atmosphere, is widely used in building roads and other public infrastructure, in response to air pollution. However, the high concentration of atmospheric pollution is often accompanied by a serious haze phenomenon, resulting in decreased efficiency of photosensitive TiO2 adsorption, the need for UV light to activate, to a certain extent, limit the promotion of new technology applications.

The seventh EU research framework programme to provide 3 million 600 thousand euros, the total R & D investment of 5 million euros, from Denmark, England, Italy, Spain and Sweden’s 14 home building materials industry enterprises to form a joint European LIGHT2CAT team. From the beginning of March 2012, after nearly 4 years of joint technical research, successfully developed a new generation of visible light response photosensitive titanium dioxide composite materials. The research and innovation activities in the traditional production process and standardized

components as much as possible, a new generation of technology will not increase the extra burden on the investment of building materials enterprises, but also to further expand the application market of a new generation of photosensitive composite materials, such as for indoor air pollutants adsorption chamber wall coating.

A new generation of technology has been the European Commission Expert Group green technology, has achieved mass industrial production of a new generation of photosensitive titanium dioxide composite material, and the promotion of pilot commercial in Denmark and spain. R & D team responsible person, the new technology to deal with the technical and economic feasibility of air pollution and the positive role of doubt.
