Advanced-Photocatalytic Materials: New Perspectives and Challenges

Dear Colleagues,

After several years of intense research, heterogeneous photocatalysis remains a promising technology for a wide range of applications. Relevant results have been described for water/air purification, production of new energy vectors via water splitting or CO₂ reduction, disinfection processes, and selective chemicals production, just to mention some examples. The TiO₂-based materials are the most explored photocatalytic candidates, although a huge range of materials has shown relevant results. Doped and composites oxides/sulfides, g-C₃N₄-based materials, metal-organic frameworks as well as well-defined structures such as modified polymers and membranes can be mentioned as relevant examples.

The current status of heterogeneous photocatalysis faces new perspectives and challenges. From a materials point of view, a continuing breakthrough in synthetic protocols has been reported. Besides, new characterization and quantification approaches have been recently described. In this collection, we are particularly interested in new green synthetic protocols as well as biomass and waste valorization opportunities. Besides, we aim to rationalize new advanced-characterization technics such as (e.g., in-situ/operando conditions) and advanced-photocatalytic quantification (e.g., photonic and quantum efficiency and theoretical calculations).

Potential topics include, but are not limited to:

• Novel photocatalytic materials and synthetic protocols
• Novel characterization approaches of photocatalytic materials
• Full use of light (UV-Vis, UV-VIS-IR) or efficient illumination sources (e.g., LEDs).
• Theoretical calculation and simulation of photocatalytic materials
• Light-matter interaction modelling and photocatalytic efficiency calculation

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. Catalysts 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 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.
