Abstract:

In this article, the effect of adding precursors condition on the physical properties of ZIF-8 compound prepared by co-precipitation method has been investigated. The physical properties, including structural properties as well as bonds formation in the synthesized compounds were studied. Also, considering the importance of porosity in ZIF-8, specific surface area, total pore volume, and other parameters related to porosity were investigated. The XRD results confirmed the synthesis of ZIF-8 structure. Also, FTIR analysis showed that the bonds were well formed in both samples. Scanning electron microscope (SEM) images showed that nanoparticles with dimensions between 80 and 110 nm were formed. It was also found that if the precursors are added slowly and drop by drop, the nanostructures with smaller particle diameter, higher specific surface area with more porosity are formed.Abstract: In this article, the effect of adding precursors condition on the physical properties of ZIF-8 compound prepared by co-precipitation method has been investigated.
