Ethylendiamine (EDA) loading on MOF-5 for enhanced carbon dioxide capture applications

Abstract

Reducing carbon dioxide levels in atmosphere presents greatest challenge in controlling global climate change. Each stage of Carbon Capture and Storage (CCS) strategy requires specialized materials. Metal-organic framework, being highly porous and crystalline materials are captivating vast scientific attention for exploring their potential in gas adsorption applications. This research work presents an attempt to synthesis post amine modified MOF materials for enhanced carbon dioxide capture applications. Thermogravimetic studies reveal that EDA MOF-5 is far more thermally stable then MOF-5; moreover synthesis can be performed successfully with recycled solvent (DMF). Carbon dioxide adsorption studies represents better carbon dioxide capture tendency for MOF-5 and EDA MOF-5 i.e., 5 mmol/g and 3.9 mmol/g respectively at 0C.
