Special Issue Information

Dear Colleagues,

Photoactive nanomaterials are receiving increasing attention due to their potential application in light-driven degradation of water and gas-phase pollutants.

The ability to exploit the strong potential of photoactive materials and access their properties relies on the ability to tune their size/shape dependent chemical-physical properties and on the ability to integrate them in photo-reactors or to deposit them on large surfaces. Therefore, the synthetic approach, as well as the post-synthesis manipulation could strongly affect the final photocatalytic properties of the nanomaterials. Thus far, a plethora of nanomaterials have been proposed for the degradation of pollutants driven by UV or Visible light: semiconductors, plasmonic nanoparticles, magnetic nanoparticles, hybrid nanocatalysts merging the properties of different crystalline domain and nanocomposite based on nanoparticles dispersed in suitable host matrix. One of the major concern in the large-scale application of nanomaterial assisted photocatalytic processes is to avoid the release of nanocatalysts in the environment during or after the photocatalytic treatment, therefore the immobilization of nanocatalyst onto suitable supports is a key point to promote their practical application.

The potential application of photoactive nanomaterials in environmental field includes abatement of organic pollutant in water, water disinfection and abatement of gas-phase pollutants in outdoor and indoor applications.

We invite contributors to submit original papers that account for recent advances in the field of photoactive nanomaterials for the degradation of pollutants assisted by UV, visible or solar light.

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 papers will be 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 monthly 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 1600 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.

ZnO-ZnS core-shell nanorods are synthesized by combining the hydrothermal method and vacuum sputtering. The core-shell nanorods with variable ZnS shell thickness (7–46 nm) are synthesized by varying ZnS sputtering duration. Structural analyses demonstrated that the as-grown ZnS shell layers are well crystallized with preferring growth direction of ZnS (002). The sputtering-assisted synthesized ZnO-ZnS core-shell nanorods are in a wurtzite structure. Moreover, photoluminance spectral analysis indicated that the introduction of a ZnS shell layer improved the photoexcited electron and hole separation efficiency of the ZnO nanorods. A strong correlation between effective charge separation and the shell thickness aids the photocatalytic behavior of the nanorods and improves their photoresponsive nature. The results of comparative degradation efficiency toward methylene blue showed that the ZnO-ZnS nanorods with the shell thickness of approximately 17 nm have the highest photocatalytic performance than the ZnO-ZnS nanorods with other shell layer thicknesses. The highly reusable catalytic efficiency and superior photocatalytic performance of the ZnO-ZnS nanorods with 17 nm-thick ZnS shell layer supports their potential for environmental applications.
