摘　　要：通过水热法制备了SnNb_(2)O_(6)/In_(2)S_(3)(SNO/IS)异质结光催化剂。采用SEM、XRD和DRS等对已合成的SNO/IS异质结材料的微观形貌、晶体结构和光学性质等进行表征。在模拟可见光下,将有机染料罗丹明B(RhB)选定为目标污染物,通过测试SNO/IS异质结材料光催化降解RhB的效率,评价其光催化活性。SNO/IS异质结光催化剂对RhB的降解效果明显优于SNO和IS。SNO与IS质量比为0.5∶1的复合材料效果最佳,在60 min内降解效率可以达到98.9%,且具有较好的光催化稳定性。SnNb_(2)O_(6)/In_(2)S_(3)(SNO/IS)heterojunction photocatalysts were synthesized by hydrothermal method.The micro-morphology,crystal structure and optical properties of the synthesized SNO/IS heterojunction materials were characterized by SEM,XRD and DRS.The organic dye rhodamine B(RhB)was selected as the target contaminant,and the photocatalytic activity of SNO/IS heterojunction materials was evaluated by photocatalytic degradation of RhB under the simulated visible-light irradiation.The experimental results demonstrated that the degradation effect of SNO/IS heterojunction photocatalyst on RhB was significantly better than that of SNO and IS.The composite with a mass ratio of SNO to IS of 0.5∶1 displayed best performance,and the degradation efficiency reached 98.9% within 60 min.The composite had good photocatalytic stability.
