Enhanced the photocatalytic activity of Ni-doped ZnO thin films: Morphological, optical and XPS analysis

Nitrogen‐Functionalized Active Carbon‐Supported Non‐Noble Nickel Nanoparticles with High Dispersity and Enhanced Catalytic Performance in Nitro Naphthalene Hydrogenation

“…The spectra clearly evidence the presence of three chemical states for nickel. The first peak around 853.0 eV is characteristic of Ni 0 , the second one presented at 855.2 eV and its satellite peak at 861.4 eV are attributed to Ni 2+ , and the third peak at 856.9 eV is due to Ni 3+ , which are consistent with previous reports . The surface compositions of Ni/AC and three different Ni/N‐AC−T are shown in Table .…”

Effect of Eu Doping on the Physical, Photoluminescence, and Photocatalytic Characteristics of ZnO Thin Films Grown by Sol–Gel Method

“…It indicates that this oxygen is in an environment of lower electron cloud (O x− ) around it ( x < 2). This O1s signal (P2) has been assigned to the oxygen vacancies generated by the incorporation of foreign cations into the lattice of ZnO . In fact, as can be seen in Figure c, the intensity of the O1s (P2) increases as the Eu concentration went from 0 to 4%.…”

Effect of Cu, Ni and Pb doping on the photo-electrochemical activity of ZnO thin films

“…Aer this percentage the grain size was found to decrease with decrease in intensity of the (002) diffraction peak. Abdel-Wahab et al 49 recorded a crystallinity degradation of ZnO thin lms upon Ni-doping. At Ni 7 wt% concentration, the (002) disappears.…”

“…Ni-doping is known to decrease the band gap of ZnO thin lms. 46,49 The decrease in the band gap has been attributed to the strong sp-d exchange interaction between the band electrons and the localized 'd' electrons of the Ni ions substituted in the Zn sites in 10 at% Ni doping level. 46,62,63 In our work the band gap was found to be constant in the case of Cu and Ni doping lms while increasing in the Pb doped lm.…”
