Extensively amino-functionalized graphene captures carbon dioxide

Abstract

The development of robust carbon dioxide (CO2) scavengers is a challenging but paramount problem of modern humanity. In the present work, we report a prospective CO2 sorbent based on amino-functionalized...

Chemical similarity of dialkyl carbonates and carbon dioxide opens an avenue for novel greenhouse gas scavengers: cheap recycling and low volatility via experiments and simulations

“…Although these thermodynamic potentials appeared positive, they are more favorable as compared to those of chemisorption. [48][49][50] Below, we discuss the enthalpic and entropic contributions and further compare scavengers exploiting chemisorption and physisorption. The increased pressure fosters physical sorption as it limits the entropic penalty corresponding to the formation of a more ordered system.…”

“…The corresponding weak electrostatic attraction does not lead to an emergence of an additional vibrational peak, as we exemplified recently in the case of the ylide-based CO 2 chemisorption. 49 Nonetheless, a reasonable similarity of the sorbent-sorbent and sorbent-sorbate binding holds promise for practical applications of the designed systems.…”

Simplified Synthesis of the Amine-Functionalized Magnesium Ferrite Magnetic Nanoparticles and Their Application in DNA Purification Method

“…Nanomaterials are continuously increasing in popularity for their advantageous properties in catalysis [ 1 ], carbon dioxide sequestration [ 2 , 3 , 4 ] and biological applications [ 5 ]. Among the various nanomaterials, magnetic nanoparticles (MNPs) are used for biological applications, such as magnetic resonance imaging [ 6 ], hyperthermia treatment [ 7 ], drug delivery [ 8 ] or the isolation of macromolecules [ 9 ], like deoxyribonucleic acid (DNA).…”
