Compiti Con Ca Co Cu Al Italiano For the aimed cuo cu 2 o heterostructures, the oxidization strategy was applied to oxidize the original cu and cu 2 o phase. fig. 1 b shows that the cu phase disappears and new characteristic diffraction peaks appear at 35.6°, 38.7°, 48.8°, and 58.2° after the oxidation strategy, which are attributed to the (−1 1 1) crystal plane, (1 1 1) crystal plane, (−2 0 2) crystal plane, and (2 0. The high density cu gbs were the preferential nucleation sites for the growth of cuo and provided channels for o diffusion, leading to the easy reoxidization of metallic cu to cu 2 o. [39, 47, 48] resultantly, the fragmented cu 2 o(111) and cu(111) grains afforded abundant cu 2 o(111) cu(111) (cu cu 0) interfaces (outlined in red) in the post cuo 160w nanosheets.

In addition, electrochemical impedance spectra (eis) and relevant fitting results indicate that the interface charge transfer resistance of s cuo cf (1.242 Ω) is smaller than that of cuo cf (1.362 Ω), cu 2 s cf (3.400 Ω), cu(oh) 2 cf (1.899 Ω) and cf (8.296 Ω), because the optimized s doped cuo surface formed by sulfur leaching and oxidative remodeling is more conducive to interfacial. At 0 v versus rhe, the cu 2 o cuo cus heterostructures showed a photocurrent of − 1.38 ma cm −2, corresponding to ~ 100% and ~ 30% enhancement with respect to cu 2 o and cu 2 o cuo respectively. Using the xrd data, the lattice parameters calculated according to the bragg's law were found to be 0.5425 ± 0.0055 nm for si wafer and n sinw, and 0.4290 ± 0.0063 nm for p cu 2 o n sinw 10 min.

The peak fit of cu 2p 3 2 peak revealing a main peak of cu 2 at 933.9 ± 0.1 ev, cu at 935.3 ± 0.1 ev accompanied by a series of satellites peaks on higher b.e. side at 942.2 ± 0.1 ev and 944.7 ± 0.1 ev and (c) depiction of oxygen 1s with peak position of o 2− phase at 529.8 ± 0.1 ev and 1s peak of oxygen vacancy (v o) adsorbed o 0 phase at 531.5 ± 0.1 ev. Second, cu 2 o and cuo display interesting and characteristic electronic structures (closed d10 shell in the case of cu 2 o and open d9 shell for cuo) due to the influence of electron correlation effects; this results in very different cu 2p photoemitted signals [15]. it is thus of particular interest to accurately determine the primary excitation spectra of these materials.
