Photocatalytic methyl orange degradation on the surface of nanoporous layers of copper, silver and their iodides

The efficiency of photocatalytic decomposition of methyl orange solutions on the surface of nanoporous layers of copper, silver and their iodides has been studied. It is shows that nanoporous layers on metal substrates have two absorption bands: they absorb radiation in the UV and Vis spectral range. The process of decomposition of methyl orange molecules on the surface of metal-semiconductor nanostructures Ag–AgI and Cu–CuI occurs under the action of UV and Vis irradiation. While transparency of the methyl orange solution increases.
