Figure 5

Experimental (solid) V K edge FT(χ(k)*k3) of dehydrated V x O y /SBA-15 (10.8 wt %) together with theoretical XAFS functions (top: "isolated VO 4 " model, bottom: addition of V-Si path to "isolated VO 4 " model). Insets show the VO4 tetrahedron (top) and a schematic representation of the V-Si path employed (bottom). Also shown are the Fourier transformed χ(k)*k3 of the individual scattering paths together with corresponding coordination number in.
