Carbon Dioxide (C02) Adsorption in MOF-5

Metal-organic Frameworks (MOFs) materials are the compounds consist of metal ions or clusters coordinated to often rigid organic molecule, forming one-, two-, or
three-dimensional structures that can be porous. It is one of carbon dioxide (CO2) Capture and Storage (CCS) which has been used mostly for separation of gas such
as, separating CO2 from the natural gas and also to reduce the anthropogenic emission of C02 to the atmosphere. These porous network structures show a great
potential compared to monoethanol amine (MEA). One of the most studied MOFs is MOF-5 due to its high surface area, flexible structure, attraction to certain gases and
cheap raw materials. Since most of the experiments are studied on hydrogen (H2) adsorption, this project is conducted with the aims to study on how much CO2can be
adsorbed/separated by MOF-5 and MOF-5 modified with multi wall carbon nanotubes (MWCNTs) and expandable graphite (EG) at the temperature of 298.15 K as well as to examine whether the modified MOF-5 can improve the adsorption of
C02. MOF-5, MWCNTs@MOF-5 and EG@MOF-5 were synthesized, characterized and then, used as the samples in the C02 adsorption experiment according to the objective of this project. The result shows that the modified MOF-5 can enhance the C02 storage compared to the pure MOF-5.
