Characterization of α-Ni(OH) by XPS

We report x-ray photoemission spectra (XPS) of beta-nickel hydroxide (β-Ni(OH)2). XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromated Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV. We present the survey spectrum (binding energy range of 0–1100 eV) measured at an analyzer energy resolution of 1.34 eV. Multiplexes of the C, O, and Ni photoemission lines, valence band region as well as the Ni LVV Auger lines were measured at an analyzer energy resolution of 0.54 eV. The research grade high purity β-Ni(OH)2 sample was obtained commercially from Chemical Company, Inc.
