| 摘要: 以离子交换法和“氟化异丙烯膜袋”水热法分别制备了AgInO2，利用XRD、低温氮吸附-脱附、SEM、紫外-可见漫反射光谱(UV-Vis diffuse reflection spectroscopy，DRS)和XPS对不同方法所得到的AgInO2进行了表征；以罗丹明B(RhB)和甲基橙(MO)为目标物，在可见光下考察了2种催化剂的光催化性能。结果表明，利用“氟化异丙烯膜袋”水热法制备的样品由于具有更好的结晶度，且在可见光区有更强的吸收，从而表现出了更好的可见光光催化活性(3 h降解RhB达94%。7 h降解MO达83%)。 |

| Abstract: AgInO2 were prepared via ion exchange method and fluoro(ethylene-propylene) (FEP) facile hydrothermal method, respectively. The as-obtained samples were characterized by X-ray diffraction (XRD), N2-Adsorption, UV-Vis diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity of the as-prepared catalysts was studied using dyes Rhodamine B (RhB) and Methyl Orange (MO)as the target degradation material under visible-light irradiation. The results indicate that the sample prepared by FEP hydrothermal method shows higher crystallinity and stronger absorption in visible light region, thus higher photocatalytic activity (94% of RhB was degraded in 3 h and 83% of MO was degraded in 7 h, respectively). |
