Some factors affecting the synthesis of ZIF-94 from zinc sulfate hetahydrate
View through CrossRef
The paper presents the first research results on the synthesis of ZIF-94 from ZnSO4.7H2O and some factors affecting the formation of ZIF-94. In this study, XRD method was used to study the crystallinity and particle size through the Scherrer equation. Nitrogen adsorption and desorption method, SEM and TEM were also used to determine the characteristics of the synthesized ZIF-94.
The research results showed that the linker, solvent, additives in the reaction components, crystallization time and temperature have significant effects on the formation of ZIF-94. Suitable conditions were also discussed for the formation of ZIF-94 with BET specific surface of 709 m2/g, average particle size of 55 nm (by SEM) and crystallinity of 100 % (by XRD).
