Abstract
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. 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.
