Selective XAFS measurements of 0.6-3.0wt% V sites on/in TiO2 were enabled utilizing a fluorescence spectrometer. The V sites were V-IV species in the case of high-surface-area V-TiO2 in contrast to V-V species in the case of conventional V/TiO2 catalysts, V supported on HSA-TiO2, and V-TiO2 prepared in the absence of dodecylamine (general sol-gel method).
