Special Issue Information

Dear Colleagues,

Nanotechnology can have a transformative impact on the way we will drive, manipulate, enhance, and monitor environmental pollution by using novel scientific findings and creating new devices based on nanoparticles. Defined by nanoscaled dimensions, nanoparticles own specific properties that can be engineered to create and manipulate their adsorption, catalytic/photocatalytic, and disinfection functionalities. Further, by assembling specific nanoscaled units we can fabricate advanced heterostructures where the ensembled units are able to join their properties for working in concert to improve their competences for environmental cleanup.

This Special Issue aims to compile a selection of original contributions and review articles regarding the applications of nanoparticles and their heterostructures in the environmental remediation. The Issue will cover a wide range of nanoparticles (organic, inorganic, or carbon-based) and their heterostructures (e.g., including but not limited to polymers, metal oxides, clays, and zeolites), not only for removing but also for controlling or for detecting pollutants from water, air, or soil.

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. Nanomaterials 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 2900 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.

Finding new technologies and materials that provide real alternatives to the environmental and energy-related issues represents a key point on the future sustainability of the industrial activities and society development. The water contamination represents an important problem considering that the quantity and complexity of organic pollutant (such as dyes, pesticides, pharmaceutical active compounds, etc.) molecules can not be efficiently addressed by the traditional wastewater treatments. The use of fossil fuels presents two major disadvantages: (1) environmental pollution and (2) limited stock, which inevitably causes the energy shortage in various countries. A possible answer to the above issues is represented by the photocatalytic technology based on S-scheme heterostructures characterized by the use of light energy in order to degrade organic pollutants or to split the water molecule into its components. The present mini-review aims to outline the most recent achievements in the production and optimization of S-scheme heterostructures for photocatalytic applications. The paper focuses on the influence of heterostructure components and photocatalytic parameters (photocatalyst dosage, light spectra and intensity, irradiation time) on the pollutant removal efficiency and hydrogen evolution rate. Additionally, based on the systematic evaluation of the reported results, several perspectives regarding the future of S-scheme heterostructures were included. Full article
