초록

염료감응형 태양전지의 광전극용 바인더로 화학적으로 기능기 작용을 가진 식물성 오일인 maleinized acrylated epoxidized soybean oil(MAESO)를 이용하였다. 제조된 광촉매의 특성을 고찰하기 위해 FE-SEM, EDS, XRD, XPS, 그리고 질소 흡착법(BET) 분석을 수행하였다. 식물성 오일 바인더를 이용하여 제조된 $TiO_{2}$ 입자는 P-25 광촉매와 비교하여 볼 때 비표면적과 특정한 크기를 갖는 세공의 수가 증가하였는데 이는 광촉매에 기능기가 증가하였기 때문이다. 기능기가 첨가된 $TiO_{2}$ 입자 표면에서 OH 관능기는 9.9에서 16.62%로 증가하였다.

Chemically functionalized plant oils, namely maleinized acrylated epoxidized soybean oil(MAESO), were used as a new bio based binders for photoelectrodes of dye-sensitized solar cells. The photocatalysts were characterized by field emission scanning electron microscope(FE-SEM), energy dispersive X-ray spectrometer(EDS), X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS) and nitrogen adsorption analyses. The surface area and number of appropriate pores were increased in the $TiO_{2}$ particles prepared using the plant oil binders in comparison with the P-25 photocatalyst, due to the larger number of functionalities. The functional groups of OH on the surface of the $TiO_{2}$ particles increased from 9.9% to 16.62%.
