Porous metal/metal-oxide nanostructured coatings produced using gas aggregation sources of nanoparticles as recyclable SERS active platforms
Original language description
In this study, we have investigated the possibility of producing highly porous metal oxide nanoparticles-based coatings decorated with Au nanostructures as a novel SERS-active and UV light recyclable platforms using a novel solvent-, linker-, and precursors-free strategy. It combines the use of magnetron-based gas aggregation sources of transition metal nanoparticles (V, Nb, and W) followed by their atmospheric pressure thermal oxidation and sputter deposition of Au nanostructures. It is shown that all investigated metal oxide/Au nanomaterials fabricated following this approach provide the SERS activity allowing the detection of methylene blue at the concentration of 10-6 M. Furthermore, it is demonstrated that while the V2O5/Au coatings cannot be effectively UV-light cleaned, Nb2O5/Au and WO3/Au coatings possess, besides SERS activity, also the ability to photodegrade MB under the UV light irradiation.
