Abstract
We have studied the surface Ni oxide by XANES techniques at the oxygen K-edge. The spectra were detected by partial yield spectroscopy, in the range of 520-570 eV at the "Grasshopper" beam line of the Frascati Syncrotron Radiation Facility. We find that the oxygen react with nickel producing an oxide where the local structure at room temperature is similar to the defective (Ni(1-δ)O). Data are interpreted following the recent electronic-configuration interaction theory.
