摘要

以硫代乙酰胺(TAA)为硫源,采用简单的一步水热法合成MgIn₂S₄复合金属硫系化物三元半导体光催化剂,并利用X射线粉末衍射(XRD)和扫描电镜(SEM)进行表征。进行光催化降解酸性湖蓝A实验,探讨了MgIn₂S₄量对样品催化性能的影响。结果表明:MgIn₂S₄的光生电子更易迁移,使复合催化剂的降解能力增强,表现出更优越的光催化性能。通过响应面优化法得出MgIn₂S₄样品最优量,并且降解30min后,降解率达到99.8%,达到较高的利用率。

Abstract

Using thioacetamide (TAA) as the sulfur source,the MgIn₂S₄ composite metal chalcogenide ternary semiconductor photocatalyst was synthesized by a simple one-step hydrothermal method and characterized further by powder diffraction (XRD) and scanning electron microscopy (SEM).The photocatalytic degradation experiment was carried out,and the influence of the amount of MgIn₂S₄ on the catalytic performance of the sample was discussed.The results showed that the photogenerated electrons of MgIn₂S₄ were easier to migrate,which enhanced the degradation ability of the composite catalyst and exhibited better photocatalytic performance.The optimal amount of MgIn₂S₄ sample was obtained by the response surface optimization method.After 30 minutes of degradation,the degradation rate reached to 99.8%,achieving a high utilization rate.
