With growth of economy, demands for the clean and safe environment are increased, whereas the air we breathe is no longer clean as much as we expect. Most of pollution come from the emission of vehicle as growing of industries and traffic volume. NOx is known as the main pollution source in urban and industrial area, which is 30% of whole pollution components. Most of Nox exists as NO type in the hot emission gas because NO is relatively stable at high temperature, but at the normal temperature NO oxidizes easily to $NO_{2}$, major pollution source. Since the pollution due to the $NO_{2}$ is regarded as serious problem, lots of plans, codes and regulations are proposed and adopted, and point and non-point pollution control methods and researches are in progress. It is difficult to control each pollution source when it is discharging the pollutant material since, most of vehicles still emit lots of pollutant gas into the air. Using the silicon based and volatile construction materials, mainly VOCs are considered harmful to the indoor air quality. Among the VOCs, the HCHO has great portion and it is cancer-causing material. To purify the air, this study is not to produce the specific methods of cleaning and preventing the each pollution sources but to make the material for cleaning the polluted air while we are living. To get this purpose, using some of the waste and the by-product of industry, environment-friendly paints are studied in this project, which will be used various construction site. Scoupe of research 1) Reference Review To review the photocatalyst mechanism internal and external reports and documents are collected and analyzed. 2) Evaluation of Photocatalyst Basic performance tests were carried out to provide the information for this study and to find the specific material which is reactive to the visible ray. 3) Making the photocatalyst carrier and paint The removal performance tests of Nox and VOCs were peformed and the removal performance was evaluated according to the mixing ratio which is researched in this study. 4) Making the NO and VOCs detctor The absorbtion performance and efficiency were evaluated based upon the result of the admixture test. 5) Producing the specific photocatalyst reactive to the low wavelength of ultraviolet light Using the result of reaction test of the low wavelength of ultraviolet light, specific photocatalyst material was chosen for the one reactive to the visible ray. 6) Making the special photocatalyst paint Theoretical review for the paint-producing process and study of the special photocatalyst material were performed to evaluate the possibility of using the new type photocatalyst paint. Results of this research 1. Production of synthetic photocatalyst material Based upon the first year research, Anatase type was chosen for the production of synthetic photocatalyst because of the activeness to the light. Oxide and sulfur synthetic photocatalyst was developed and it was reactive under the visible ray. 2. Pollution removal test of furnace slag, photocatalyst carrier and cray, photocatalyst carrier The more metathesis ratio of carrier, the higher removal ratio were happened. However, it was not enough of a difference among of 10%, 20% and 30% metathsis ratio of carrier. In comparison metathesis ratio of carrier, 10% metathesis ratio of carrier is most efficient to remove harmful chemical substance. 3. Test of inorganic paint and study of its capacity In case of NOx at UV light, the eliminative ability was better than different harmful materials, On the other hand in case of $CH_{3}CHO$, removal performance appeared low compared with HCHO and VOCs(toluene). In case of a fluorescent lamp, of elimination capability was not enlarged so much rather than UV light. Against elimination of the harmful materials, it appeared that the efficiency was not surpass. Because quantity of ultraviolet ray in a fluorescent lamp is smaller than UV light.
