  The urgent need for sustainable and innovative approaches to mitigate the
increasing levels of atmospheric CO$_2$ necessitates the development of
efficient methods for its removal. In this study, we focus on the synthesis and
functionalization of metal-organic framework (MOF) ZIF-8 at room temperature to
enhance its capacity for CO$_2$ capture. Specifically, we investigated the
impact of four amino-compounds, namely tetraethylenepentamine (TEPA),
hexadecylamine (HDA), ethanolamine (ELA), and cyclopropylamine (CPA), on the
chemical structure, size, surface area and porosity and CO$_2$ capturing of
ZIF-8 powder. By varying concentrations of the amino-compounds, we examined
their influence on the ZIF-8 properties. These results highlight the potential
of simple synthesis and functionalization techniques for MOFs in enhancing
their CO$_2$ capture capabilities. The findings from this study offer new
opportunities for the development of strategies to mitigate CO$_2$ emissions
using MOFs.
