대형 스모그 챔버를 이용한 TiO2의 NO 저감 효능 평가 Assessment of NO Reduction using TiO2 in Large-Scale Smog Chamber Abstract A large-scale environment chamber was built to test the efficiency of NO reduction to apply the real-road systems using TiO2, which is a relatively inexpensive and easy to handle material in the past 20 years. In general, TiO2 is a semiconductor material with a band gap of 3.2 eV, corresponding to a wavelength of 390 nm. Three types (i.e., power, black, white block) of TiO2 were tested to investigate NO reduction. As a result. power TiO2 was shown for the best NO reduction up to 72% (overall average of 40.8% at 120 min.) rather than white (23.0%) and black block (15.8%) impregnated by TiO2. For an implication, the inorganic secondary products under the condition of reactive oxygen species from TiO2 should be considered for a further study.
