| 제목 | Enhanced photocatalytic activity and stability of ZnS-CdS/ZnO nanocomposite under visible light irradiation |
| 초록 | The visible light responsive ZnS-CdS/ZnO materials were successfully fabricated by a precipitation method and used as photocatalysts in photocatalytic degradation of Rhodamine B. The CdS was used as a photosensitizing agent to activate ZnO due to its narrow direct band gap and ZnS was also deposited on the ZnO to increase the efficiency and stability of the system. The prepared samples were characterized by X-ray diffraction and UV-vis diffuse reflectance spectroscopy. The prepared samples show high crystallinity. The absorption spectrum extends to the visible light range. As expected, the experiments of photocatalytic degradation of Rhodamine B show that ZnO/ZnS-CdS exhibit much higher photocatalytic activity and recycle stability compared to pure ZnO sample under visible light irradiation. |
