Реферат:
V-51 static and MAS NMR spectroscopy of central transition is shown to be an effective method for the characterisation of strongly bonded V(V) species in VOx/TiO2 catalysts. Simultaneous determination of quadrupole and CSA tensors parameters (i.e., C-Q, eta(Q), delta(sigma), eta(sigma)) from both static and MAS NMR spectra of central transition permits the extraction of all NMR parameters with a reasonable accuracy. For the first time, a large V-51 quadrupolar constant (14-16 MHz) has been obtained for strongly bonded V(V) species in a supported vanadia catalyst, whereas CSA tensor principal components were found to be very close to those for bulk vanadium (V) oxide.
