초록

본 연구에서 종래의 졸-겔법을 사용하여 Fe-ACF/$TiO_2$ 광촉매 복합체를 제조하였고, 이들 광촉매의 분해능은 메틸렌블루 (MB) 용액의 분해에 의하여 나타내었다. 제조된 이들 복합체에 대한 입자크기, 표면구조, 결정상 및 원소분석을 BET, SEM, XRD 및 EDX에 의하여 각각 특성화 하였다. 가시광선 조건에서 분해된 MB 농도에 대한 스펙트라는 UV/Vis 분광기에 의하여 얻어 졌다. 이와 같이 얻어진 스펙트라는 MB의 제거된 농도로부터 광촉매 활성을 입증하였다. 이들 광촉매 활성은 가시광선 조건에서 복합체 광촉매 내에 존재하는 ACF, $TiO_2$ 및 Fe 사이에 강력한 시너지 반응에 의해 유도된 것으로 여겨진다.

In present study, a conventional sol-gel method was used to prepare Fe-ACF/$TiO_2$ composites, a kind of composite photocatalysts, whose capability was evaluated by degrading methylene blue (MB) solution. The particle size, surface structure, crystal phase and elemental identification of the composites prepared were characterized by BET, SEM, XRD and EDX, respectively. The spectra of MB concentration degraded under visible light were obtained by UV/Vis spectrophotometer. These obtained spectra demonstrated the photocaltalytic activity from removal concentrations of MB. It was considered that these photonic activities are induced by a strong synergetic reaction among ACF, $TiO_2$ and Fe in the composite photocatalysts under visible light.
