Morphological features of micro- and nanoporous silver and copper films synthesized by the substitution reaction method

The results of a study the structural features thin silver and copper films synthesized by chemical substitution reaction are presented. Silver were obtained immersing substrates in solution nitrate. Copper iron tin-plated sulfate solution. morphology composition layers was carried out using scanning electron microscope. It has been shown that metal nanoporous up to 1 μm thick formed on as early 2-3 s after start reaction. consist microcrystalline hexagonal plates micro- nanodendrites. As time increases, become denser. In this case, minimum pore size is 20 nm. can be used for photocatalytic decomposition water enhancement Raman scattering.
