Single-Atom Catalysts for Environmental Remediation and Resource Recovery: From Preparation to Applications

Dear Colleauges,

In the last decade, single-atom catalysts (SACs) have received vast attention in the areas of energy, chemical, and environmental engineering. Two properties of SACs are critical: high atomic efficiency and high atom-substrate binding stability. The former ensures low cost, especially for precious noble metals. The latter, which is often achieved via oxygen vacancy, dopant coordinations, and spatial confinement, is important for long-term and large-scale applications. For environmental remediation, SACs have been applied for (1) gas phase: VOC treatment, NOx reduction, CO2 reduction, and CO oxidation; (2) aqueous phase: Fenton-like advanced oxidation process (AOP), dehalogenation, and nitrate reduction. The application of SACs for environmental engineering is still at an early stage, with challenges remaining in terms of improving pollutant conversion efficiency, understanding the fundamental SAC catalysis mechanisms, and constructing physicochemically stable SACs in various environmental media. This Special Issue aims to include original research or review articles related to the application of SACs for environmental remediations and resource recovery, with subjects covering novel material designs, theoretical calculations, and engineered applications.

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 250 words) can be sent to the Editorial Office for assessment.

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. Molecules 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 2700 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.
