Photocatalytic Degradation of Organic Wastes in Water II

Dear Colleagues,

In recent years, public concerns have arisen about environmental pollution by so-called emerging organic pollutants (EOPS) in water sources and factory effluents, because of their potential adverse effects on human health and aquatic ecosystems. A large number of physical and biological processes have been proposed to remove pollutants from water, but they do not completely remove the majority of EOPs. Advanced oxidation processes (AOPs) based on catalytic, electrochemical, and photochemical reactions are currently available and are able to degrade a large number of pollutants. An important group of AOPs is represented by photocatalytic processes, in which luminous radiation produces the electronic activation of the semiconductor material that constitutes the catalyst. TiO₂ is one of the most widely applied materials as photocatalysts in water decontamination, both alone and in combination with other materials acting as doping agents and/or material supports. However, the use of this semiconductor material presents known disadvantages; therefore, it is very important to continue working on the search for new, more efficient photocatalysts with better performance.

This Special Issue on “Photocatalytic Degradation of Organic Wastes in Water II” is intended to cover the progress and new trends in the preparation and characterization of photocatalytic materials, with particular emphasis on their applications in environmental remediation for the removal of emerging organic pollutants from different types of water.

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.
