Abstract
With an ever increasing need for a more energy-efficient and environmentally benign
procedure for gas separation, adsorbents with tailored structures and tunable surface
properties are in high demand. Metal–organic frameworks (MOFs), constructed from metalcontaining
nodes connected by organic bridges, are such a new type of porous materials.
They are promising candidates as adsorbents for gas separations due to their large surface
areas, adjustable pore sizes and controllable properties, as well as acceptable thermal
stability. However, the bottleneck in this context is that MOFs are expensive to be fabricated
and majority of them are not stable in harsh environments, which are often required by
industrial processes. In this thesis, we introduce three families of metal-organic frameworks
with exceptional gas separation performance for a variety of different gas mixtures
separation. Their unique separation performances are well supported by isotherm
measurement, X-ray crystallography, DFT calculations, and breakthrough test. These MOFs
are all readily synthesizable by inexpensive precursor and highly stable at extreme
conditions.
