in-situ solvothermal growth of mof on the capillary fused silica aiming to use as stationary phases in gas chromatography

Metal–organic frameworks (mofs) have received great attention as novel substrate in separation sciences because of their fascinating structures and unusual properties such as large surface-to-volume ratios, high levels of porosity, and selective adsorption of different materials. in the road to goals of this subject, several mofs have been proposed to be as stationary phase in gas and liquid chromatography. in this work, we reported the simple and effective in-situ method for immobilization of special mof on the surface of fused silica capillaries aiming to use as a stationary phase in the gas chromatography. the method includes in-situ solvothermal growth of mof on the surface of the fused silica capillary. the results of the data obtained from sem, ft-ir, xrd and bet have indicated that the mof nanoparticles were successfully immobilized and bonded on of the surface of the fused silica capillary.
