Particularly, the number of carbon atoms bonded to the nitrogen atom affects the pKa of the amine site, resulting in greater CO2 binding strength. In addition, the proportions of carbamate anion, ammonium cation, and (bi)carbonate species in the solvent vary according to various factors such as...
1d, the reduction peaks in H2-TPR were attributed to the reduction of the Mo-O species on Mo2N. It was noticed that even at 950 °C, the H2 consumption was still found, demonstrating that part of the oxygen atoms was strongly coordinated with Mo atoms and were very hard to be ...
As explained above, Δiarelates to the amount of charge transferred from the metal surface to the adsorbate during the adsorption process. The charge is transferred from the Fermi level of the metallic slab to the adsorbate. Due to this, the Fermi level seems like an intuitive choice for pre...
Electrocatalytic CO2reduction reaction (CO2RR) is an attractive way to simultaneously convert CO2into value-added fuels and chemicals as well as to store intermittent electricity derived from renewable energy. However, this process involves multiple proton and electron transfer steps and is kinetically ...
1., 2., 3. The thermodynamically metastable OVs, which are formed through hydrogen reduction or hydroxyl dehydration, facilitate the incorporation of CO2 oxygen atoms into the oxide sublattice, enabling subsequent CO2 hydrogenation. More recently, heterogeneous catalysts with solid surface frustrated ...
The synthesis of C2+products with two or more carbon atoms from direct CO2hydrogenation via C–C coupling and carbon chain growth is attractive, as these products have a high energy density and can be used as basic chemicals for polymer synthesis or liquid fuels for transportation. Similar to ...
Ozone quantum yields from mixtures of oxygen with N2O2N2 and CO2, photolyzed at 1470 , are investigated to determine relative rates of reaction of 1D oxygen atoms with the admixed gases. The data are expressed with respect to the rate of reaction with CO2 for comparison with similar data obt...
The number of lattice oxygens of H-form zeolites located around Al in (AlO4)(-) units was affected by the environment of the central Al atoms in the framework of the zeolites. Consequently, the number of base sites was dependent on zeolite topology. Zeolites diverse in the location of T...
the coordination environment of each assembled Ni atom is the same as that of the Co in Cu6-Co, in which two NiIIcenters are coordinated with four water molecules and two O atoms in mna ligands, respectively. To vary the coordination environment of catalytic centers, we introduced bidentate ...
Catalytic reduction of CO2 over Cu-based catalysts can produce various carbon-based products such as the critical intermediate CO, yet significant challenges remain in shedding light on the underlying mechanisms. Here, we develop a modified triple-stage
