A Mechanism for Selectivity in Heterogeneous Redox Catalysis

Selective acceleration of metal cation oxidation by silver halide in the presence of silver nanoclusters is observed only when the diameters of the cations correspond to the spacing of the regularset of interatomic hollows of the catalyst surface; this is probably associated with their longer retention in the reaction zone due to the increase in the coordination number in the coincidentally occurring compact packing.
