Abstract

During the process of producing potassium fertilizer from salt lake resources, a large amount of waste liquid brine, rich in raw materials such as magnesium chloride, is generated. In this work, a MoS2/MgAl-LDH composite material was constructed using the secondary hydrothermal technique. Characterizations including X-ray diffractometer (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) confirmed the distribution of MoS2 nanosheets on the surface of MgAl-LDH. Under full-spectrum irradiation, the degradation efficiency of Rhodamine B reached 85.5%, which was 69.2% higher than that of MgAl-LDH alone. The results from the electrochemical, UV-Vis, and XPS-VB tests indicate that the internal electric field accelerated the separation and transportation of charge carriers between MoS2 and MgAl-LDH. These findings demonstrate the great potential of MoS2/MgAl-LDH as a photocatalyst in the degradation of organic dyes, which will aid in the green recycling utilization of magnesium resources from salt lake by-products.

MoS2/MgAl-LDH复合材料光降解罗丹明B染料的研究

盐湖资源在生产钾肥的过程中，会产生大量的废液卤水，其中富含氯化镁等原料。本文采用二次水热法制备了MoS2/MgAl-LDH复合材料。x射线衍射仪（XRD）、扫描电镜（SEM）和x射线光电子能谱（XPS）等表征手段证实了MgAl-LDH表面存在MoS2纳米片。在全光谱照射下，罗丹明B的降解效率达到85.5%，比MgAl-LDH单独降解效率提高了69.2%。电化学、UV-Vis和XPS-VB测试结果表明，内部电场加速了MoS2和MgAl-LDH之间载流子的分离和输运。这些研究结果表明，MoS2/MgAl-LDH作为光催化剂在降解有机染料方面具有很大的潜力，这将有助于盐湖副产物镁资源的绿色循环利用。
