www.nature.com/scientificreports OPEN Efficient CO2 adsorption using chitosan, graphene oxide, and zinc oxide composite Farnoush Fathalian 1, Hamidreza Moghadamzadeh 1*, Alireza Hemmati 2* & Ahad Ghaemi 2 This study was deeply focused on developing a novel CTS/GO/...
The amine compounds can be protonated in acidic solution environment since the nitrogen atom in the amine groups is with sp3 hybridization and has one lone pair of electrons, which can fill the empty 1s orbital of H+ and form a coordination bond. As a result, the amine group becomes ...
In all samples, the bending and scissoring vibrations of N–H occurred at 1430 and 1575 cm−1, respectively, suggesting that the amino group is present in these samples. Also, a broad peak around 3434 cm−1 is related to the stretching vibration of the O–H bond in the ...
This is demonstrated by the very high dissociation energy (750 kJ/mol) for each C=O bond, higher than the respective values for C-C (336 kJ/mol), C-O (327 kJ/mol) or C-H (441 kJ/mol) bonds [135]. Thus, any attempt to use CO2 as a reactant must take into consideration the...
As crosslinking tightens the polymer chain and lowers the gas diffusivity, the improvement is also believed to be contributed to by the inter-molecular hydrogen bonding between the cross-linkers and 6FDA-ODA's hydrogen bond donor/acceptor groups (–CF3, –C=O, –CN– and –C–O–C– [24...
The surface engineering strategies for improved CO2 adsorption, activation, and product selectivity will be reviewed. In addition, theoretical calculations along with in situ characterization techniques will be in the spotlight to clarify the kinetics and thermodynamics of the reaction process. The aim ...
Classify the compound as ionic, polar covalent, or nonpolar covalent based on the bond type and geometry: CCl_4. Classify the compound as ionic, polar covalent, or nonpolar covalent based on the bond type and geometry: N_2. Disting...
9. A cosmetic composition comprising (a) at least a ginger root CO2 extract as defined in claim 4, at least one compound selected from (b1), (b2) and (b3): (1)1) at least one UV filters, (b2) at least one skin lightening agent, (b3) at least an antioxidant, and at least one...
The inclusion of cocatalyst may assist in facilitating (increasing the Faradaic efficiency) the production of and/or influencing the type of carbon products produced by the CO2 reduction reaction produced by the present invention. The cocatalysts are incorporated into the polymer coating by mixing the...
