Now, problems about indoor air pollution is risen with indoor hours of person's life is increased about average 20.3 times a day. By that building is shut tightly while ventilation was felt constraint for energy efficiency. So human's health be in threat by over 80 thousand harmful things include bacillus and chemical substance etc. Indoor air was polluted better than outdoor air because it is not circulated well than outdoor air. Now, many efforts to reduce volatility gas that is produced in existent building materials by doing coercive ventilation or green materials to keep away indoor air pollution. Also, mix charcoal in coating material to protect breeding mold or bacillus.
In this treatise, removing indoor pollutant by using photocatalyst. This photocatalyst is getting big popularity, because it is harmless in human body. However, Usually, photocatalyst purifies foul air in case of receive ultraviolet rays, and can't remove foul air in visible ray area. Therefore, performance drops in indoor that ultraviolet rays are feeble. There is photocatalyst that react visible ray area on present. However, it is expensive price and limitative use extent. it should be economical, and high-volume mass production should be available by finish for construction that purify indoor air to use. Informed method that dop ion to photocatalyst is thermal treatment, hyrothermal synthesis, psychrophile work precipitation method etc. Heat treatment that route of this is the simplest is the most economical. Therefore, in this research, transition element doped using heat treatment.
Therefore, in this research, that make photocatalyst by purpose, do reacting in visible ray area by do doping some transition metal elements(Cr, Cu, Al, Na, Fe) in state that treat Thermal treatment. Treated with heat 6 hours by 1000℃. Did gas hundred experiments, XRD analysis, DRA analysis for performance analysis. As a result, phtocatalyst doped Cr and Cu became the most superior reactivity in visible ray area.
