Our study gives an explanation, showing that zinc hydroxide possesses a highly unstable nature resulting in rapid degradation and leading to the formation of zinc oxide during standard XPS measurements. Abstract: A detailed investigation of a potential corrosion product of zinc – zinc hydroxide – using X-ray photoelectron spectroscopy (XPS) was performed to shed light on remarkable inconsistencies in the literature reported reference data, being the key element for the evaluation of the unknown experimental spectra.
The decomposition is driven by X-ray radiation and cannot be suppressed totally.Formed ZnO critically complicates the identification of Zn(OH) 2.Zn(OH) 2 rapidly decomposes to ZnO during the standard XPS measurement. X-ray photoelectron spectroscopy (XPS) study revealed that the beneficial effect on the corrosion resistance of ZnCoMo coatings has a passive layer which, initially, is composed of Zn (OH) 2, ZnO, Mo (IV) oxide, and hydroxide and small amounts of Co 3 O 4 3.XPS being important study for the analysis of chemical state and composition at the.
Zn(OH) 2 is studied in detail by means of the X-ray photoelectron spectroscopy. LMM auger peak analysis revealed the presence of Zn interstitials.
