Abstract
On this study, visible-light responsive photocatalyst prepared by sol-gel method was evaluated the effect of the reduction of volatile organic compounds (VOCs) occurred in vehicle interior and its property was examined. According to UV/visible result, visible-light responsive photocatalyst was found that the UV-visible peak is red shift at 420nm, is sensitive in the visible light region. With vehicle interior parts and materials coated visible-light responsive photocatalyst, VOCs was measured by GC/MS. Measuring the VOCs generated from vehicle interior parts and materials, the reduction of VOCs was confirmed.
가시광촉매를 이용하여 자동차 내장재에서 발생하는 VOCs의 저감 효과를 알아보았다. 가시광촉매는 sol-gel법으로 제조하였으며 UV-vis peak가 420 nm에서 적색이동 되어 가시광영역에서 감응하는 것으로 나타났다. 이러한 특성을 갖는 가시광촉매를 자동차 내장재에 코팅처리하고, 자동차 내장재에서 발생하는 VOCs를 측정한 결과 분해 저감율이 우수하게 나타났다.
