Abstract

$SnO_{2}$-doped anatase type $TiO_{2}$ powder was prepared by the polymerization complex route from tin(IV) bis (acetylacetonate) dichloride, titanium diisopropoxide bis (acetylacetonate) and polyethylene glycol (PEG) as a complexing agent. The structural changes of reaction mixture were monitored by fourier transform infarared (FT-IR) spectroscopy. The microstructure and morphology 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.

$SnO_{2}$가 도핑된 아나타제형의 $TiO_{2}$ 분말을 tin (IV) bis (acetylacetonate) dichloride와 titanium diisopropoxide bis (acetyl- acetonate)를 출발물질로, polyethylene glycol (PEG)을 첨가하여 합성하였다. 반응과정에 대한 구조변화를 FT-IR로 추적하였고, 입자의 모양과 형태 및 결정의 구조는 FE-SEM과 XRD 분석기로 관찰하였다. 합성된 분말의 광촉매 효과는 환경오염물질로 indigo carmine (IC)을 선택하여 UV-visible 스펙트라로 관찰하였다.
