【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%)。更多还原

【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).更多还原
