New Perspectives in Photocatalytic Water Treatment

Dear Colleagues,

Over the past 30 years, photocatalysis has been recognized for its potential in water treatment. In a photocatalytic transformation, the activation of a chemical reaction or its rate is changed when a semiconductor photocatalyst adsorbs photons (in the ultraviolet or visible radiation range) with an energy sufficiently high to generate excited electron-hole pairs. The excited state of the photocatalyst interacts with the contaminants in water, forming reaction intermediates, which can be harmless or harmful. In turn, the latter can be degraded into non-hazardous compounds. Considering the huge research efforts focused on TiO₂ (and other photocatalytic materials) for the oxidative degradation of organic pollutants, it is surprising that, due to the low photoconversion efficiency, the industrial applications of water treatment of various photocatalytic materials and technologies are still very limited. This Special Issue will cover all relevant topics related to photocatalytic oxidative processes in water treatment, with a special emphasis on progress and investigations, which are required for improving their practical use. Articles presenting advances into photocatalytic processes or showing a correlation between the synthesis, structure, and performance of photocatalytic systems are welcome. On the basis of our experience, the following topics are particularly required: (i) water treatment and photocatalytic advanced oxidation processes; (ii) visible light active photocatalyst preparation, characterization, and applications,; and (iii) inactivation of microorganisms, kinetics, and mechanism.

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. Water 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 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.
