Abstract

Abstract In this article, silicotungstic acid (STA)-loaded metal–organic framework (MOF)-derived composites (C-STA@ZrO2) were successfully synthesized by simple strategies. X-ray diffraction, Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray, N2 physisorption, UV-vis diffuse reflection spectroscopy, and X-ray photoelectron spectroscopy techniques were used to characterize the as-obtained composites. Intriguingly, C-STA@ZrO2 exhibits excellent photocatalytic performance, and rhodamine B (RhB) (40 mg·L−1) in water can be degraded to 93.9% after 120 min of irradiation. Moreover, various catalysts, catalyst dosage, and dye concentrations on RhB degradation were evaluated. Besides, the reusability of C-STA@ZrO2 was also investigated. This work may provide a new and significant guideline for exploring excellent performance of MOF-derived hybrid material for wastewater purification.

负载杂多酸的MOF介孔氧化锆催化剂化学降解罗丹明B

摘要本文成功合成了硅钨酸(STA)负载金属有机骨架(MOF)衍生复合材料(C-STA@ZrO2)。利用x射线衍射、傅里叶变换红外、扫描电镜、能量色散x射线、N2物理吸收、紫外-可见漫反射光谱和x射线光电子能谱等技术对所得复合材料进行了表征。有趣的是，C-STA@ZrO2表现出优异的光催化性能，在120 min的照射下，水中40 mg·L−1的罗丹明B (rhodamine B, RhB)可降解至93.9%。此外，还考察了不同催化剂、催化剂用量和染料浓度对RhB降解的影响。此外，还对C-STA@ZrO2的可重用性进行了研究。本研究为探索mof衍生杂化材料在废水净化中的优良性能提供了新的重要指导。

期刊介绍： Green Processing and Synthesis is a bimonthly, peer-reviewed journal that provides up-to-date research both on fundamental as well as applied aspects of innovative green process development and chemical synthesis, giving an appropriate share to industrial views. The contributions are cutting edge, high-impact, authoritative, and provide both pros and cons of potential technologies. Green Processing and Synthesis provides a platform for scientists and engineers, especially chemists and chemical engineers, but is also open for interdisciplinary research from other areas such as physics, materials science, or catalysis.
