Carbon Capture Material

Over the years, greenhouse gases have overwhelmingly risen by nearly 35 billion tons an-

nually, and it’s threatening the environment with severe detrimental effects for years to

come. According to the United Nations, 45% of CO2 emissions need to be cut of by 2030.

This work is a step towards this goal where we synthesized a material that is cost-effec-

tive, scalable, and highly efficient in CO2 capture. Zeolite Imidazolate Frameworks (ZIFs)

are a sub-class of Metal Organic Frameworks (MOFs) where zeolites affiliate organics as

linkers and are characterized by high surface area (highly porous) that enable them to

have applications such as gas separation.

ZIFs are also characterized by high intrinsic

thermal and chemical stability. Linking it to a polymer to form what is called a Mixed ma-

trix membrane (MMM). However, when MMMs are formed, they would combine the

advantages of inorganic fillers and organic polymeric membranes. Ion exchange and

robustness in a processable polymer matrix surpass this upper bound, which limits the rela-

tionship between the selectivity and permeability of CO2 in the material.

With an outstanding high permeability/selectivity with amine modification, it increases the CO2 up-

take since it is targeted by the membrane to be captured through Direct Air Capture

(DAC) with the alteration of pressure the material adsorbs/desorbs.

%320 of the material's

properties were witnessed, and %150 more compared to literature work. After the extrac-

tion, many uses of CO2 come to life, such as synthetic fuel production, synthesis of chem-

icals like alcohols, urea production, and soft drink carbonation.
