Exploration of Metal-Organic Frameworks with Active Single-Metal Atoms in Its Nanospace for Gas Adsorption

Isolated coordinatively unsaturated single-metal atoms (SMAs) stabilized in porous structure have emerged as extraordinary
materials with exciting physicochemical properties due to their unique intrinsic chemical nature and electronic features. This can be exploited
for the activation of small molecules and efficient catalyst design. The purpose of this experiment is to elucidate the interaction between
coordinatively unsaturated single-metal atoms of alkali metal ions (e.g. Li+, Na+, K+ , Ca+2 ) and small molecules (e.g. CO2, C2H4, O2)
within the confined nanospace of microporous anionic metal-organic framework M@Y(tppo)(HCOO) (M= Li+, Na+, K+ and Ca+2 ).
