ABSTRACT

Received 21 May 2020
Revised 21 Jun 2020

Accepted 30 Nov 2020

 

A kind of 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 room temperature. Subsequently, Ag nanoparticles (AgNPs) loading on bimetallic frameworks were prepared by a facile impregnation method in acetone solvent. Both ZnCo-ZIFs and Ag/ZnCo-ZIFs were analyzed by several characterization techniques including powder X-ray diffraction (PXRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (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 were successfully loaded on the ZnCo-ZIFs with content of 18.42%. Ag/ZnCo-ZIFs in this combination may pave a way for preparing a kind of heterogeneous catalyst to remove organic compounds from aqueous solutions.
