Synthesis, and characterization of metal-organic frameworks -177 for static and dynamic adsorption behavior of CO2 and CH4

In this work, a microporous metal organic framework (MOF-177) was synthesized and characterized to investigate the static and dynamic adsorption behavior of CO2 and CH4. The synthesized MOF-177 was found to be six-dimensional shaped channels with an average pore diameter of 1.18 nm. The characteriza...
