Special Issue Information

Dear Colleagues,

For many years, scientists have been attracted by noble metals and their properties. Nevertheless, only recent development of experimental techniques allowed us to design and characterize noble-metal-doped thin films. This multi-disciplinary research effort aims to develop a firm understanding of the properties of noble metals encapsulated within or deposited on the library of matrices at our disposal. This Special Issue aims to gather scientists working on the design of noble-metal-doped thin films and coatings for scientific and engineering applications.

We seek contributions dealing with the design and fabrication of novel types of thin films and coatings containing or modified with noble metals for a broad range of applications. In this context, micro- and nanoscale experimental methods based on thin film preparation procedures as well as characterization methods based on microscopy and spectroscopy techniques allowing for a full understanding of the properties of noble-metal-doped thin films will be favored.

Scientists are encouraged to present their most recent contributions concerning the transfer of knowledge obtained during the preparation and/or characterization of noble-metal-doped thin films, including their practical applications.

The Special Issue will cover, but will not be limited to, the following topics:

Innovative methods for thin films preparation:

  • one or multi-step processes for the preparation of noble metals with various compositions and morphologies on ceramic, polymer, carbon, and other types of coatings/substrates;
  • noble metal bulk composites and nanocomposites, metallic nanostructures and nanoparticles, bimetallic systems, and multilayers;
  • highly ordered arrays of noble metal nanoparticles and coatings.

Applications:

  • analytical applications and sensors;
  • catalysis and photocatalysis;
  • solar and fuel cells;
  • electronic and optical applications;
  • medical and biological systems.

Novel experimental approaches based on microscopy and spectroscopy characterization techniques:

  • HR-TEM, SEM, AFM, OM;
  • XPS, FT-IR, UV-Vis, XRD, QCM, etc.

This work is focused on photocatalytic properties of titanium dioxide thin coatings modified with silver nanostructures (AgNSs) and graphene oxide (GO) sheets which were analyzed in processes of chemical transformations of rhodamine B (RhB) under ultraviolet (UV) or visible light (Vis) irradiation, respectively. UV-Vis spectroscopy was applied to analyze the changes in the RhB spectrum during photocatalytic processes, revealing decolorization of RhB solution under UV irradiation while the same process coexisting with the transformation of RhB to rhodamine 110 was observed under Vis irradiation. The novelty of this study is the elaboration of a methodology for determining the parameters characterizing the processes occurring under the Vis irradiation, which enables the comparison of photocatalysts’ activity. For the first time, the method for quantification of rhodamine B transformation into rhodamine 110 in the presence of a semiconductor under visible light irradiation was proposed. Photocatalysts with various surface architectures were designed. TiO2 thin coatings were obtained by the sol-gel method. GO sheets were deposited on their surface using the dip-coating method. AgNSs were photogenerated on TiO2 or grown spontaneously on GO flakes. For characterization of obtained photocatalysts, scanning electron microscopy (SEM), X-ray diffraction (XRD) and diffuse-reflectance spectroscopy (DRS) techniques were applied. The results indicate that the surface architecture of prepared coatings does not affect the main reaction path but have an influence on the reaction rates and yields of observed processes.
