- Abstract
Metal–organic frameworks (MOFs) have garnered significant attention across various fields, particularly in the field of the separation sciences, owing to their appealing structures and unique properties including high surface-to-volume ratios, substantial porosity, and selective adsorption capabilities for diverse materials. On the road to objectives of this study, numerous MOFs have been proposed as stationary phases in both gas and liquid chromatography. This study presents a straightforward and efficient in situ method for immobilizing a specific MOF onto the surfaces of fused silica capillaries, with the aim of utilizing them as stationary phases in gas chromatography. Diverse pre-treatments of the fused silica capillaries and various coating methods, including dynamic coating and different in situ solvothermal growth techniques for MOF deposition onto the capillary surface, were systematically undertaken and meticulously examined. Results obtained from different of analytical techniques, including FESEM, EDX, FTIR, and XRD, affirm the successful immobilization and bonding of MOF nanoparticles onto the fused silica capillary surface. The prepared MOF@capillary emerges as a promising candidate for serving as a stationary phase in gas chromatography, particularly for the separation of various volatile organic compounds. This comprehensive study not only expands our understanding of MOF applications but also confirms the feasibility of employing MOF-coated capillaries in gas chromatographic separation processes.
