As a Lewis acid, CO2 can be captured by alkaline media such as KOH and amine solutions, yielding (bi)carbonate and carbamate, separately. As CO2 release from capture media causes extra capital costs and energy loss (Fig. 4a), direct conversion of CO2 in capture media offers an appealing av...
The crystal structure was solved by direct methods with SHELXT65 program, and was refined by full-matrix least-square methods with SHELXL65 program contained in the Olex2 suite66. Weighted R factor (Rw) and the goodness of fit S were based on F2, conventional R factor(R) was based on ...
Nature has awarded us the plethora of energy, which is around ∼ 1370 W/m2 (Johnson, 1954), and therefore, it must be harvested to fulfill the ever-growing global energy demand (Lewis and Nocera, 2006). Natural photosynthesis process is the first ever known blueprint of recycling CO2 to...
dehydrogenation of propane, and especially a catalyst with large CeO2size was beneficial for re-oxidation with CO2. It is difficult to improve the performance of the sole CeO2in heterogeneous catalysis probably for the low specific surface area (SBET) and single pore structure. Thus, the ...
Carbon dioxide is ubiquitous and a vital molecule for maintaining life on our planet. However, the ever-increasing emission of anthropogenic CO2 into our atmosphere has provoked dramatic climate changes. In principle, CO2 could represent an important one
On the left side of the graph, the presence of lighter metal oxides is observed, which shows that the shorter the bond distance, the greater the adsorption energy. This is consistent with the nature of this interaction, which is a Lewis acid–base reaction. Similarly, Figure 6 shows the ...
Figure 6. C=O couple structure. The bonding electrons (EL): The number of electrons taking part in a bond. C=O bond is covalent, and Carbon and Oxygen share two electrons each. So, C and O have 4 bonding electrons. EN stands for electronegativity. Following the general formula [37...
(Figs.2BandS25), manifesting once again the importance of the Co-Npyrcovalent bond to avoid catalyst detachment. The use of barep-CTF-pyorp-CTFmixed with dissolvedCoTCPcin the parallel systems could not initiate the formation of CO as well (TableS5), which highlights the importance of pre-...
Lewis Acids and Bases: As per the ideology behind the Bronsted-Lowry and Lewis acid-base theory, a Lewis acid is a chemical species which can accept electrons and is electron deficient. A Lewis base is a chemical species which is electron rich in nature and can readily d...
