A Cu2p Xps Spectra And B D O1s Xps Spectra Of The Three Cu 2 This cus cu 2 o cuo cu heterostructure electrocatalyst reached a high fe of 84% for formate production at the potential of À0.7 v vs. rhe with a current density of À20 ma cm 2 . Compared to the other stable oxide, i.e., cuprous oxide (cu 2 o), the bond lengths of cu o in cupric oxide are pretty lengthier, i.e., 1.88 a 0 and 1.96 a 0 [98]. unlike cuprous oxide, which has octahedral symmetry, cuo has square planner symmetry, as the 2 cu o bond lengths perpendicular to the plane are much higher.

Silabas Ca Co Cu The gradual change from cuo to cu 0 is also indicated by the intensity decrease of the cu o bond (1.94 Å) and the intensity increase of the cu cu (2.53 Å) bond (fig. 4d, e). These results reveal that the cu atom in cuo coordinates with four o atoms (cu–o 4), which is different from the cu (n–cu–o 3) in n–cuo with three o atoms and one n atom (fig. 3f). A coordination of bidentate type is expected between the carboxylate ion and the cu(ii) of cuo [15]. in addition to the bidentate product, the peak at 1564 cm −1 also represents the formation of covalent bond between the –oh on the surface of cuo, producing (–c(o)–ocu). a similar behavior was also observed by li et al. [16]. We imagine that while cu ions from cu 2 o are oxidized to cu 2 during the pulses at 2.5 v, a certain time is needed for these ions to react with the btc molecules and to form mof nanocrystals.

The formation of cu cu 2 o cuo nanocomposites is confirmed by powder x ray diffraction, whereas the w h plot revealed the average particle size of nanocomposite approximately 17 nm, which is in good agreement with the scherrer method and transmission electron microscopy analysis. the uniform distribution of cu and o elements was supported by the elemental mapping of the nanocomposite. Figure 6. (a) cuo(110):cu, (b) cuo(110):cu–o, and (c) cuo(110):o surface structures after relaxation. left panel shows the side view of the (2 × 2) supercell, while the top view of a (1 × 1) cell is shown in the right panel. in side view figures, we have shown a (2 × 2) supercell for a clear visualization of bonding and atomic arrangements.
