To establish an accurate X-ray photoelectron spectroscopy method for quantifying mixed nickel metal, oxide, hydroxide, and oxyhydroxide states and detecting low levels of Ni(III) species.
Acquired reference standard spectra for Ni, NiO, Ni(OH)2, and NiOOH to enable systematic spectral subtraction.
Combined data analysis of Ni 2p and O 1s core-level spectra to evaluate commercial nickel powder and a thin nickel oxide film grown at 1-Torr O2 and 300 °C for 20 minutes.
Assessed analysis depth using calculated inelastic mean free paths and examined relative sensitivity factor uncertainties (Ni 2.67 ± 0.54).
Successfully demonstrated qualitative detection of low concentrations of Ni(III) and quantitative separation of mixed oxidation states via reference spectral subtraction.
Validated chemical state quantification across commercial nickel powder and thin oxide films while detailing the impact of sensitivity factor variance (2.67 ± 0.54).
