Abstract
The zeolitic-imidazole frameworks (ZIFs) have become popular due to their uniformly structured cavities and portals of framework dimensions, which make them suitable for numerous applications. In order to access pores and functional surfaces, thermal activation is significantly post-treatment on the synthesis of ZIFs for their applications. This study explores the impact of different thermal activation conditions on two- to three-dimensional ZIFs, which significantly affect their structure, morphology, and properties. Their transform structure is evidenced by integrated X-ray diffraction technique, Thermogravimetric analysis, Scanning electron microscope, and Fourier transform infrared spectroscopy. Moreover, the performance of greenhouse gas adsorption (CO2 and CH4) applications is affected by the transformation through the thermal activation of materials. Therefore, understanding the activated conditions that impact material synthesis is crucial to maximizing the potential applications of ZIFs in various fields. The 2D ZIF-L has more exposed external surfaces and open structures, which makes it more reactive towards adsorptive reactants, unlike the 3D ZIFs. The 3D ZIFs have a robust structure and a higher porosity framework that can withstand challenging application conditions. Thus, it's essential to ensure appropriate activation conditions to maintain the functional properties of ZIFs, which are crucial for their optimal performance in various applications.
