The density functional theory (DFT) calculation is further performed to understand H2dissociation on O-defective α-Ga2O3(001). As illustrated in Fig.3d, the H2heterolytic dissociation releases large energies of 1.65 eV first. The resulting hydride tends to migrate to the neighboring O atom,...
nanosheets. The high-resolution TEM image (Fig.S13b) further displayed well-resolved lattice fringes with planar spacings of 0.260 and 0.268 nm, which closely fit the (0 1 2) and (1 0 1) lattice planes of α-Ni(OH)2, respectively. FigureS14shows a high-angle annular dark-field sc...
2 molecule with a O–C–O angle of 134.3° (structure 3 in Figure 7). The formation of carboxylates, also known as carbonites, is thermodynamically driven even at 25 °C by the adsorption of CO on a surface oxygen according to: CO(gas) + O2−...
The C=N bond count decreased significantly, suggesting that the FeN4 coordination structure is rather stable. 3.4. XPS XPS is an instrumental method that has significant value in the investigation of SACs by providing insights into their elemental composition and enabling the characterization of the ...
1. An obvious diffraction peak at 2θ = 1.0° corresponding to p6mm hexagonal symmetry of mesoporous structure, is detected in the small-angle XRD patterns (Fig. S1), which evidences a formation of mesoporous Al2O3 materials (Yuan et al., 2008). No characteristic peaks of K2O species is...
