dc.description.abstractStructural evolution of vanadium (V) and molybdenum (VI) oxides with temperature was studied by Time Differential Perturbed Angular Correlation (TDPAC) spectroscopy in different atmospheres with 111Cd probe incorporated by wet impregnation. In case of V2O5 sealed in vacuum, the critical temperature for probe diffusion was found to be above 500oC, whereas for MoO3 this barrier was 600oC. The diffusion was suppressed in low pressure oxygen atmosphere. The behavior of hyperfine parameters on heating to melting point of V and Mo oxides and subsequent cooling to room temperature was analyzed. TDPAC results were complemented by X-ray diffraction data. We discuss comproportionation, topotactic, competitive and consecutive mechanisms as the candidates to describe V2O5 → VO2 and MoO3 → MoO2 reduction.pt_BR
