X-ray absorption spectroscopy study of the local structure of heavy metal ions incorporated into electrodeposited nickel oxide films

Relevancy:  

JES

X-ray absorption study of electrochemically grown oxide films on Al-Cr sputtered alloys. I. Ex situ studies

Relevancy:  

JES Oxides grown electrochem. in borate buffer soln. on surface of sputter-deposited AlCr alloy films were studied by X-ray absorption near edge structure (XANES). Measurements were made in air immediately following polarization in soln. Oxides were examined with X-ray photoelectron spectroscopy. Effects of alloy composition and thickness as well as applied potential were studied. Cr(VI) was found in oxides if applied potential was sufficiently high. Cr(VI) was enriched at interface with electrolyte and proportion of Cr(VI) in oxide was higher for alloy films containing more Cr. Cr(VI) in oxides could be reversibly reduced to Cr(III) and reoxidized to Cr(VI) by subsequent potentiostatic treatments in soln.
