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 TiO2 입자는 P-25 광촉매와 비교하여 볼 때 비표면적과 특정한 크기를 갖는 세공의 수가 증가하였는데 이는 광촉매에 기능기가 증가하였기 때문이다. 기능기가 첨가된 TiO2 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 TiO2 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 TiO2 particles increased from 9.9% to 16.62%.
