초록

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.
