우리는 탄소 전구체로 활성탄 (AC), 활성탄 섬유 (ACF)와 탄소나노튜브 (MWCNT)와 티타늄 전구체로써 TNB를 사용하여 탄소-TiO2 복합체를 제조하였으며, 이들의 특성을SEM, TEM, BET, XRD와 EDX를 이용하여 분석하였다. 그리고 이들의 광촉매 활성은 UV 램프 조사에서 일정한 농도의 MB 용액을 이용하여 측정하였다. UV조사한 후에 MB의 농도는 UV-vis 분광광도기를 이용하여 측정하였다.
We used activated carbon (AC), activated carbon fiber (ACF) and multi-walled carbon nanotube (MWCNT)as carbon sources and titanium n-butoxide as titanium source to prepare carbon-TiO2 composites. For characterization their properties, scanning electron microscopy (SEM), transmission electron microscopy (TEM), BET surface area, X-ray diffraction(XRD) and energy dispersive X-ray analysis (EDX) were used. And the photoactivity of the carbon-TiO2 composites, underUV irradiation, was tested using the fixed concentration of methylene blue (MB, C16H18N3S·Cl·3H2O) in aqueous solution. After UV irradiation for a certain time, the concentration of MB solution was determined by UV-vis absorption spectroscopy.
