Popis: | A bimetallic Zn/Co zeolitic imidazole frameworks (ZnCo-ZIFs) was successfully synthesized from 2-methylimidazole and two metal salts including zinc nitrate, cobalt (II) nitrate by a solvothermal method at the room temperature. Subsequently, Ag nanoparticles (AgNPs) loading on bimetallic frameworks was prepared by a facile impregnation method in acetone solvent. Both ZnCo-ZIFs and Ag/ZnCo-ZIFs was analyzed by several characterization techniques including X-ray powder diffraction (PXRD), scanning electron microscope (SEM), Fourier transform infrared spetroscopy (FT-IR), thermogravimetric analysis (TGA) and energy-dispersive X-ray spectroscopy (EDX). The results showed that ZnCo-ZIFs crystals had sodalite structure, high thermal stability and AgNPs was successfully loaded on the ZnCo-ZIFs with content of 18.42%. Ag/ZnCo-ZIFs in this combination may pave a way for the preparation a kind of heterogeneous catalyst to remove organic compounds from aqueous solutions. |
