摘要
通过离子交换沉淀法制备了AgI/Bi-BTC复合物,利用XRD、FTIR、SEM-EDX及UV-Vis等技术对制备的催化剂的结构、表面形貌及光学特性进行了表征,并研究其对罗丹明B的光催化降解。结果表明,相较于AgI,AgI/Bi-BTC复合物对可见光的吸收能力明显提高;在可见光下降解60mg/L罗丹明B,反应40 min后降解率达93.4%,且经过3次循环实验后AgI/Bi-BTC仍具有光催化活性。
AgI/Bi-BTC composites were prepared by ion exchange precipitation method.The structure,surface morphology and optical properties of the obtained composites were characterized by XRD,FTIR,SEM-EDX,UV-Vis spectroscopy,and the photocatalytic performance of AgI/Bi-BTC for the degradation of Rhodamine B was evaluated.The results showed that the visible light absorption capacity of AgI/Bi-BTC was significantly higher than that of AgI.The degradation rate of Rhodamine B was 93.4%under visible light degradation for 40 min,and AgI/Bi-BTC still had photocatalytic activity after three cycles of experiments.
