Charge transfer effects and O2- vacancies in pure CuO nanofibers and enriched with 3.0% Mn

Electronic and Magnetic Contribution for CuO and CuO Nanofibers Doped with Mn at 3.0%

“…For this analysis, two samples, A-NFs and B-NFs (CuO doped with 3.0% Mn) were taken for comparison. To corroborate the distribution of Mn and its percentage can be observed in the reference [33].…”

“…Panel a show the pure CuO NFs showing the Cu (yellow) and O (red) components, furthermore, this can be corroborated with the signals obtained from the EDS analysis (see panel b). The distribution of the elements in the mapping NFs showed homogeneity, in a 1:1 ratio (see reference [33]).…”

“…Analysis of 2p spectra can be complicated to distinguish the ion structure and charge effect of neighboring bonded ions as both the oxidation state and the multiplet splitting can be affected by this perturbation. These phenomena have been observed principally in copper oxide [5,32,33].…”

“…Furthermore, the study of the multiplet structure of CuO has not been generated in recent years unlike the undersigned of this manuscript [26,33], therefore, authors Okada and Kotani to extend and determine the data obtained [25]. These authors studied three Cu oxides by approximation calculations using a Hamiltonian proposing the energy of the free ion (Cu) and the gap (electronic repulsion due to its neighboring O 2p atom) in the BV, binding the energy level Cu 2p 6 3d 9 4s 2 and its final state 3d 8 L (where L denotes the gap and the relationship with O 2p).…”

Synthesis of organic–inorganic hybrid nanocomposites modified by catalase-like catalytic sites for the controlling of kiwifruit bacterial canker

“…Mn 2+ and Mn 4+ , the peaks at 653.1 eV are attributed to Mn 2p 1/2 features of Mn 2+ /Mn 4+ , which provide the structural basis for the enzymatic reactions. [57][58][59] High-resolution XPS spectra of C 1s, N 1s and O 1s furtherly conrmed successful PDA loading onto ZnO NPs. The XRD pattern of ZnO@PDA-Mn displayed that all the diffraction peaks were consistent with the ZnO crystal, which proves that Mn ions may coordinate on the PDA coating (Fig.…”
