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.
