Synthesis, Characterization and Modification of Metal Organic Framework-235 for Carbon Dioxide Adsorption

Reducing anthropogenic carbon dioxide (CO2) emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues in this era. There are both natural and human sources of CO2 emissions. Natural sources include decomposition, ocean release, respiration and volcanoes. Human sources come from activities like cement production, deforestation and the burning of fossil fuels. Carbon capture and storage (CCS) from large point sources such as power plants is one option for reducing CO2 emissions. While a variety of technologies and methods have been developed, the adsorption of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of capture materials with high adsorption performance and low capital cost are of paramount importance. Metal-organic frameworks (MOFs), a new class of crystalline porous materials constructed by metal-containing nodes bonded to organic bridging ligand shows a great potential as adsorbents or membrane materials in gas separatation. Related with the title of the project, this project will focus on synthesis, characterization and modification of MOF-235 and it is believed can give impressive result in the adsorption ability of CO2. Thus, MOF-235 can be a good alternative method in reducing CO2 emission.
