Abstract: Based on NGR parameter analyses IS. A, W, and f’(T)]. we have studied the genesis of the states of .%-containing components of catalysts prepared by impregnating the prechlorinated y-AIZOz with a solution containing a mixture of complex anions, [PtCI,SnCI$ and [PtCl?(SnCI&]? ~. At the initial step, Sn-containing compounds interacted with OH or Cl atoms of the support surface. Two types of Sn(lV), three to four states of Sn(II). and several Pt-Sn alloys were identified after reduction of samples with H, at 823 K. The amount and composition of Sn(ll) 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.
