Figure 6From: Structural characterization of vanadium oxide catalysts supported on nanostructured silica SBA-15 using X-ray absorption spectroscopyExperimental (solid) V K edge FT(χ(k)*k3) of dehydrated V x O y /SBA-15 (10.8 wt %) together with a theoretical XAFS function (i.e. "isolated V 2 O 7 " model). Inset shows the V2O7 dimer. Also shown are the Fourier transformed χ(k)*k3 of the individual scattering paths together with corresponding coordination number in brackets.Back to article page
