Interaction between Pt(IV) and Pd(II) chloro complexes in solution and on the γ-Al2O3 surface

The conversions of a mixture of platinum(IV) and palladium(II) chloro complexes in aqueous solution and on the gamma-Al2O3 surface at 25-150A degrees C are reported. Heat treatment can initiate interaction between the complexes, both dissolved and adsorbed. The hydrolysis of the chloroplatinate ion is accelerated by the palladium chloro complex, whose composition remains unchanged.
