The effect of synthesis procedure on the catalytic performance of isostructural ZIF‐8

Abstract

We demonstrate the synthesis of isostructural zeolitic imidazole framework (ZIF‐8) using four distinct synthetic methods. Subsequently, the variations in physicochemical properties were analyzed through the catalytic reaction of CO2 cycloaddition of epoxide. It was thus demonstrated that simply by changing the type of synthetic method for the preparation of ZIF‐8, the physicochemical properties were changed significantly which in turn influenced the catalytic activity of ZIF‐8. It was found that the synthetic method affected the crystal growth and consequently influenced the physicochemical properties which are crucial aspects in metal–organic framework applications. There is an almost exponential relationship between the reactivity of various ZIF‐8 samples in CO2 cycloaddition of epoxide and the surface area, CO2 adsorption and pore volume.

“…The same peaks can be found in all samples at 7.40, 10.43, 12.7, and 18.0°, which correspond to the diffraction planes (011), (002), (112), and (222), respectively, which are consistent with the XRD patterns of MOFs. 39 The data demonstrates that ZIF-8 exhibits great crystallinity and that all samples are in pure phases and are isostructural, indicating that there are sufficient binding proteins to produce cocrystallization, that is, uniform tiny molecules of biofluids. 40 The DLS analysis revealed the particle size distribution of the Zn−Co, Zn−Cu, and Zn−Ni MOFs, with an average size of 442.5 ± 10.96 nm for Zn−Co, 1362 ± 37.72 nm for Zn−Cu, and 1069 ± 29.87 nm for Zn−Ni (Figure 3a and Table S-1 In complex biosamples, metabolites are selectively trapped and identified via LDI.…”

“…However, the limitation with the microwave method is the rapid nucleation and crystal growth, which results in higher amount of crystal defects and low internal surface area (Mousavi et al, 2018).…”

Synthetic Factors Affecting the Scalable Production of Zeolitic Imidazolate Frameworks

“…ZIF-8 with a cubic morphology could be changed to a rhombic dodecahedron with time. Each stage is proved by many experiments. ,,,,− It is worthwhile to point out that different morphologies can bring different catalytic effects.…”
