Abstract

$CNT/TiO_2$ composites were prepared by using multiwall carbon nanotubes (MWCNT) and various titanium alkoxide precursors. The composites were comprehensively characterized by scanning electron microscopy (SEM), field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and UV-vis absorption spectroscopy. The photoactivity of the prepared materials under UV irradiation, was tested using the conversion of MB from model aqueous solution. Finally, according to the results of methylene blue (MB) removal experiment, we could see that sample CTOS have better MB removal effect than samples CTIP and CTPP.

MWCNT 와 여러 가지 티탄 알콕사이드 전구체를 사용하여 $CNT/TiO_2$ 복합제를 제조하였다. 이들 복합체들은 SEM, FE-SEM, XRD, EDX 및 UV-vis 분광기를 사용하여 종합적으로 분석하였다. UV 조사하에서 MB모델 수용액의 변이에 대한결과로부터 제조된 물질에 대한 광활성을 시험하였다. 마지막으로 MB 제거 실험의 결과에 따르면, 시료 CTOS의 경우 시료 CTIP 및 CTPP의 경우보다 우수한 MB제거 효과를 나타내었다.
