초록

실온의 초음파 조건에서 질산 아연과 수산화 나트륨을 각각 물과 알코올 용액에서 반응시켜 산화 아연(ZnO) 나노입자를 합성하였다. 풀러렌($C_{60}$)과 ZnO 나노입자들은 전기로를 이용하여 각각 $700^{\circ}C$ 에서 2 시간 동안 가열하였다. 풀러렌($C_{60}$)과 ZnO 나노입자들의 형태와 광학성질은 XRD, SEM, TEM 과 UV-vis spectroscopy를 이용하여 분석하였다. 가열한 $C_{60}$과 ZnO 나노입자, 비가열한 $C_{60}$과 ZnO 나노입자를 각각 methylene blue(MB), methyl orange(MO), rhodamine B(RhB)용액에서 UV-vis spectroscopy를 사용하여 광촉매 분해반응을 연구하였다.

Zinc oxide(ZnO) nanoparticles were synthesized by reacting an aqueous-alcoholic zinc nitrate solution to sodium hydroxide under ultrasonic irradiation at room temperature. The fullerene($C_{60}$) and ZnO nanoparticles were heated individually in an electric furnace for two hours at $700^{\circ}C$. The morphology and optical properties of the $C_{60}$ and ZnO nanoparticles were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM) and ultraviolet/visible (UV-vis) spectroscopy. The photocatalytic activity of the heated and unheated the $C_{60}$ and ZnO nanoparticles for the decomposition of methylene blue(MB), methyl orange(MO) and rhodamine B(RhB) was examined using UV-vis spectroscopy.
