The metals chemical states in hydrated vanadium oxides.

The X-ray photoelectron spectroscopy (XPS) spectra of hydrated vanadium oxides (VO)Mo(x)V(12-x).nH(2)O (x=0, 1, 2, 3) were studied to provide the vanadium ions reduction ratio (RR)=V(4+)/(V(4+)+V(5+)) dependence on the molybdenum ions concentration and thermal treatment. The vanadium valence does not depend on Mo doping (x View Article and Find Full Text PDF
