Photocatalytic Surfaces for Environmental Applications

Dear Colleagues,

Photocatalysis is an emerging and promising technology involving the activation of a semiconductor by UV or visible light, with artificial light sources or natural sunlight. Considered as a laboratory process for many years, it is now enjoying development resulting from simultaneous efforts by research laboratories and industrials in the search for innovative solutions to the environmental treatment (liquid and gaseous effluents and surfaces) or for the energy production and storage. However, in many applications, it is essential to immobilize the semiconductor on a suitable support to form a photocatalytic film or develop incorporated materials. This is particularly the case for the air treatment, self-cleaning surfaces, but also for the H₂ production by water splitting on a semi-industrial scale.

This Special Issue is devoted to “Photocatalytic Surfaces for Environmental Applications”. In particular, the topics of interest include, but are not limited to:

• Photocatalytic surfaces for depollution of water, air and soil;
• Immobilized photocatalysts, novel substrates and functionalized surfaces;
• Structured hybrid photocatalysts (adsorbent-photocatalysts, cementitious materials, etc.);
• Self-cleaning surfaces;
• Novel Vis photocatalysts;
• H₂ production by water splitting;
• Energy storage;
• Antimicrobial surfaces;
• Protection of buildings, contruction materials;
• Solar 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 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. Coatings 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 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.
