The decreasing amount of fossil fuels and increasing threat of global warming from the pollutants have driven the search for clean energy source. Energy sources from fossil fuels still remain in the forefront despite being a major source of increased CO2 content in the atmosphere. Metal Organic Frameworks (MOFs) have emerged as promising materials for hydrogen storage and CO2 sequestration. Several factors influencing the hydrogen uptake of porous MOFs such as surface area, catenation, ligand functionalization, doping with alkali metals and unsaturated metal centers have been extensively studied. Similarly, well defined periodicity and tunable pore sizes along with less basic amino-functionalized MOFs enables them favorable for fast and reversible CO2 gas adsorption at low partial pressure and room temperature. In this review we present diverse aspects of metal organic frameworks like fluorination, amino functionalization for high hydrogen storage and CO2 sequestration capabilities.
