XANES and XPS studies of the reduction of ammonium paramolybdate

PDF Version Also Available for Download.

Description

in situ glancing-angle x-ray reflectivity experiments were performed on electrochemical reduction products formed in a dilute paramolybdate solution on a platinum electrode. These data were compared with x-ray photoelectron spectra which showed formation of simple molybdate, pentavalent and tetravalent species at increasingly negative potentials. X-ray absorption data demonstrated changes in edge position, pre-edge structure and edge height corresponding to reduction and subsequent growth of the reduction product film at a number of the potentials examined with XPS.
