Abstract

Adsorption coupled with photocatalytic degradation is proposed to fulfill the removal and thorough elimination of organic dyes. Herein, we report a facile hydrothermal synthesis of MIL-100(Fe)/GO photocatalysts. The adsorption and photocatalytic degradation process of methylene blue (MB) on MIL‐100(Fe)/GO composites were systematically studied from performance and kinetic perspectives. A possible adsorption‐photocatalytic degradation mechanism is proposed. The optimized 1M8G composite achieves 95% MB removal (60.8 mg/g) in 210 min and displays well recyclability over ten cycles. The obtained MB adsorption and degradation results are well fitted onto Langmuir isotherm and pseudo‐second order kinetic model. This study shed light on the design of MOFs based composites for water treatment.

MIL-100(Fe)/GO 复合材料对亚甲基蓝的光催化降解:性能和动力学研究
吸附与光催化降解相结合,可实现有机染料的去除和彻底清除。在此,我们报告了一种简便的水热法合成 MIL-100(Fe)/GO 光催化剂的方法。从性能和动力学角度系统研究了亚甲基蓝(MB)在 MIL-100(Fe)/GO 复合材料上的吸附和光催化降解过程。提出了一种可能的吸附-光催化降解机理。优化后的 1M8G 复合材料在 210 分钟内实现了 95% 的甲基溴去除率(60.8 mg/g),并在十次循环中显示出良好的可回收性。所获得的甲基溴吸附和降解结果与 Langmuir 等温线和伪二阶动力学模型十分吻合。这项研究为设计基于 MOFs 的水处理复合材料提供了启示。

期刊介绍: The International Journal of Coal Science & Technology is a peer-reviewed open access journal that focuses on key topics of coal scientific research and mining development. It serves as a forum for scientists to present research findings and discuss challenging issues in the field. The journal covers a range of topics including coal geology, geochemistry, geophysics, mineralogy, and petrology. It also covers coal mining theory, technology, and engineering, as well as coal processing, utilization, and conversion. Additionally, the journal explores coal mining environment and reclamation, along with related aspects. The International Journal of Coal Science & Technology is published with China Coal Society, who also cover the publication costs. This means that authors do not need to pay an article-processing charge.
