Abstract
AbstractWe demonstrate enhanced dye adsorption capacity of nanoclay by decoration with chromium‐based MOF (MIL‐101) nanostructure. The Clay/Cr‐MOF composite exhibits a crystalline structure with high thermal stability. Moreover, it shows the superior specific surface area (4959 m2/g) and porosity which is beneficial for wastewater treatment. The developed Clay‐MOF composite exhibits superb adsorption capacity toward various organic dyes as compared with existing materials. The adsorption experiments revealed high adsorption capacity and selective dye removal efficiency of MOF‐modified nanoclay with reusability for multiple regeneration cycles. The adsorption kinetics was found to obey the pseudo‐second‐order kinetic model. These findings provide new insights into the application of such porous adsorbents for wastewater treatment applications.
