Abstract

$SnO_2$-doped $TiO_2$ powder was obtained from tin (IV) bis(acetylacetonate) dichloride and titanium diisopropoxide bis(acetylacetonate) with quinacridone as the dye sensitizer molecule. The structural changes of the reaction mixture were monitored by fourier transform infrared (FT-IR) spectroscopy. The morphology and microstructure of gel powder were studied by field-emission scanning electron microscopy (FE-SEM) and X-ray diffractometry (XRD). The photocatalytic activity of these powders with the anatase structure was investigated by using indigo carmine solution as a test dye

$SnO_2$가 도핑된 $TiO_2$ 분말을 tin (IV) bis(acetylacetonate) dichloride와 titanium diisopropoxide bis(acetylacetonate)를 출발물질로, 유기염료인 quinacridone을 첨가하여 합성하였다. 반응 전후 염료의 구조를 FT-IR로 관찰하였고, 입자의 모양과 형태 및 결정의 구조는 FE-SEM과 XRD 분석기로 알아보았다. 환경오염물질로 유기염료인 indigo carmine을 선택하여 관찰한결과, 아나타제 구조를 갖는 quinacridone이 첨가된 분말을 합성하여, 가시광선 영역에서 광분해 효과를 관찰할 수 있었다.
