Abstract: Based on NGR parameter analyses [δ, Δ, W and f'(T)], we have studied the genesis of the states of Sn-containing components of catalysts prepared by impregnating the prechlorinated γ-Al2O3 with a solution containing a mixture of complex anions, [PtCl3SnCl3]2− and [PtCl2 (SnCl3)2]2−. At the initial step, Sn-containing compounds interacted with OH or Cl atoms of the support surface. Two types of Sn(IV), three to four states of Sn(II), and several Pt-Sn alloys were identified after reduction of samples with H2 at 823 K. The amount and composition of Sn(II) components of the catalyst tend to change most dynamically due to a strong interaction of some of the Cl ions and Sn atoms with the support lattice. The problems encountered in the application of the method are discussed.
