Special Issue Information

Dear Colleagues,

We invite you to contribute to this Special Issue of Materials entitled “New Insights of Nanocomposite Materials for Photocatalytic Applications ”. Photocatalytic nanocomposite materials have a huge potential to both limit the production of pollutants and to mitigate against the effects of existing environmental contamination. They also make it possible to overcome the limitations of conventionally used photocatalytic materials, such as the lack of visible light response and low quantum efficiency. This Special Issue aims to cover recent trends and the latest research advances in the field of thin photocatalytic nanocomposites production, characterization, and application to such aspects as environmental remediation, clean manufacturing, and green energy production.

In particular, the topics of interest include but are not limited to the following:

  • Photocatalytic nanocomposites for depollution and disinfection;
  • Nanocomposite energy storage materials;
  • Nanocomposites for H2 production by water splitting;
  • Graphene and graphene-based materials;
  • Nanocomposites for membranes and filters;
  • Nanocomposites for self-cleaning and anti-fouling surfaces;
  • New production and characterization techniques of photocatalytic nanocomposites.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Composites of Ag and TiO2 nanoparticles were synthesized in situ on cotton fabrics using sonochemical and solvothermal methods achieving the successive formation of Ag-NPs and Ti-NPs directly on the fabric. The impregnated fabrics were characterized using ATR-FTIR spectroscopy; high-resolution microscopy (HREM); scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS); Raman, photoluminescence, UV-Vis, and DRS spectroscopies; and by tensile tension tests. Results showed the successful formation and impregnation of NPs on the cotton fabric, with negligible leaching of NPs after several washing cycles. The photocatalytic activity of supported NPs was assessed by the degradation of methyl blue dye (MB) under solar and UV irradiation revealing improved photocatalytic activity of the Ag–TiO2/cotton composites due to a synergy of both Ag and TiO2 nanoparticles. This behavior is attributed to a diminished electron–hole recombination effect in the Ag–TiO2/cotton samples. The biocide activity of these composites on the growth inhibition of Staphylococcus aureus (Gram+) and Escherichia coli (Gram−) was confirmed, revealing interesting possibilities for the utilization of the functionalized cotton fabric as protective cloth for medical applications.
