Evaporation of Ni and carbon containing species onto NiO/Ni as case study for metal support catalysts investigated by Metastable Induced Electron Spectroscopy (MIES)

Growth of nickel nanoparticles on NiO/Ni(001): Evidence of adsorbed oxygen on metal particles by metastable induced electron spectroscopy (MIES)

“…On top of this oxide layer nickel was deposited stepwise from a rod in an electron beam evaporator. In contrast to the former study [18] where nickel was evaporated from a graphite crucible we expected to exclude the occurrence of hydrocarbons on the deposited nickel.…”

“…The NiO layer grown on Ni(0 0 1) has been characterised by XPS, MIES and UPS before and was discussed in [18]. It shows the typical spectral features of NiO but also a small metallic contribution from the underlying Ni(0 0 1) substrate in XPS and UPS.…”

“…We have studied Ni deposition on NiO films before [18]. A comparison of the UP and MIE spectra of this study with those in [18] shows that the UP spectra are very similar representing the growth of metallic nickel and the attenuation of the underlying oxide layer.…”

“…In a previous communication [18], we have successfully applied this algorithm to spectra obtained during nickel deposition on a NiO layer grown on Ni(0 0 1). Not only that we could reconstruct different reference spectra for the oxide and deposited nickel atoms.…”

Investigation of structural, morphological and optical properties of nickel zinc oxide films prepared by sol–gel method

“…Furthermore NiO films are suitable for magnetoresistance sensors, chemical sensors [6,7], electrochromic devices [8] and transparent p-type semiconducting layer, smart windows [9] and dye sensitized photocathodes [10][11][12]. Some methods can be used for the preparation of NiZnO films such as sputtering [13], evaporation [14], electrodeposition [15], thermal decomposition [16], pulse laser deposition (PLD) [17][18][19], spray pyrolysis [20], and sol-gel techniques [21]. Among these methods, the sol-gel method is an attractive one due to its simplicity, safety, non-vacuum system of deposition, and inexpensive.…”
