Abstract

In this report, we present a simple, swift mechanochemical synthesis of metal-organic frameworks (MOFs) using a kitchen grinder. By adopting this tool, we could synthesize ZIF-8, CuBTC and MIL-100(Fe) in multi gram-scale and successfully employed MIL-100(Fe)-KG for the efficient (ca. 98%) removal of organic dye (methylene blue) from aqueous solution. Indeed, we demonstrated the significance of pore window for effective dye adsorption by comparing the adsorption behaviour of ZIF-8-KG and MIL-100(Fe)-KG. We believe that this approach could be of economic interest towards the greener synthesis of porous adsorbents for waste-water treatment.
