The good permeability of CO2 through the Pure Matrimid and all of the three MMMs may be attributed to the smaller kinetic diameter of CO2, its polar nature, and creation of significant interactions between the CO2 molecules and the polar groups present in the Matrimid structure. These are the ...
The α and β peaks were observed on the nonpolar and the stepped surfaces, and the γ peak was observed on the polar surface. The α peak was assigned to adsorption on a surface Zn O pair, and the β peak was assigned to adsorption on an anion vacancy or a step. While adsorbed ...
orthorhombic β-Mo2C(001) Mo-terminated polar surface provokes the spontaneous cleavage of a C-O bond in CO2 and carbon monoxide formation, whereas on a β-Mo2C(001) C-terminated polar surface or on a δ-MoC(001) nonpolar surface the CO2 molecule is activated yet the C-O bond prevails....
Solvent effects were investigated for selective hydrogenation of acetophenone (AP) with commercial 5% Pd/Al2O3 and 5% Pd/C catalysts using polar and nonpolar solvents. The rate of AP hydrogenation varied with the solvents used in different ways depending on the catalysts used. The highest AP ...
Membrane-based gas separation exhibits many advantages over other conventional techniques; however, the construction of membranes with simultaneous high selectivity and permeability remains a major challenge. Herein, (LDH/FAS)n-PDMS hybrid membranes, con
To adjust the thermodynamic coefficients of the equation for a more precise estimation of the physical properties of the system, several physicochemical aspects of the system should be evaluated, such as the characteristics of the donor and the acceptor of the hydrogen bond of the molecule. ...
The different solvents employed were polar (dimethyl formamide, acetone), protonic (isobutanol), mild polar (ethyl acetate, chloroform), and nonpolar (octane). The results are shown in Figure 7. The perovskite was decomposed by most of the solvents studied due to their strong polarity and the ...

In general, CO2solubility can be enhanced by employing organic solvents instead of aqueous solutions as electrolytes. Despite CO2being a nonpolar molecule, it exhibits considerable polarizability and can form hydrogen bonds with compatible donor solvents. The majority of organic electrolytes are polar solv...
Electrochemically reducing CO2 to more reduced chemical species is a promising way that not only enables the conversion of intermittent energy resources to
