초록
본 연구에서 쉽고 빠른 마이크로 조사법을 사용하여 합성한 Cu2Se-그래핀 나노복합체를 광촉매 분해 효과를 연구하였다. 제조된 나노복합체는 XRD, SEM, TEM, 라만분광분석, XPS 및 UV-Vis 흡수분광법을 사용하여 특성화하였다. 그리고 광촉매 분해특성을 가시광선 조사하에 표준염료인 로다민 B의 분해를 통하여 연구하였다. Cu2Se-그래핀 복합체는 상당히 우수한 광촉매 분해 효과를 나타내었고, 이는 180 min 동안 가시광선 조사하에서 약 95%의 분해 효과를 나타내고 있음을 이들 결과로부터 알 수 있었다. 결론적으로 Cu2Se-그래핀 복합체는 염료 오염물질에 대한 적합한 촉매로 사용할 수 있음을 확인하였다.
Here, we examined the photo-degradation efficiency of Cu2Se-graphene nanocomposites synthesized by a facile and fast microwave- assisted technique. The prepared composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, XPS and UV-Vis spectrophotometry. The photocatalytic performance was studied through the decomposition of Rhodamine (Rh B) as a standard dye under visible light radiation. A 95% of Rh B degradation after visible light irradiation for 180 min indicates that the Cu2Se-graphene composite exhibited significant photodegradation efficiency. Therefore, it can be concluded that the synthesized Cu2Se-graphene can be used as a suitable catalyst for decomposing dye pollutants.
