Title: Chemical synthesis of thin films and supported crystals by oxidation of zintl anions

Abstract

A process is described for sensitizing a surface of a substrate which consists of: selecting an organic, inorganic or metallic substrate composed predominantly of a supporting matrix reducibly by a polyatomic main group metal anion in a redox reaction by the transfer of electrons to the substrate, forming a solution of a salt composed of alkali metal cations and polyatomic main group metal anions, treating the surface with the solution to oxidize the main group metal anions, to reduce the substrate by the transfer of electrons thereto and the formation thereby of a negatively charged matrix, to transfer the alkali metal cations to the substrate, and to deposit the main group metal on the surface of the substrate to form a modified surface of the substrate, and treating the modified surface with a solution of a salt of a transition metal cation to extract at least a portion of the alkali metal cations from the substrate and deposit the transition metal in elemental form on the modified surface.
