摘要：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 pho-tocatalytic 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.
