Special Issue Information

Dear Colleagues,

Around the globe, the environment has been steeply deteriorating due to, among other factors, several human activities (food, pharmaceutical and fuel production, waste management, travelling, communications, etc.). The actions to remediate such a phenomenon can be classified into two large groups: preventive and corrective. For both of them, however, photocatalyzed processes emerge as a promising alternative and, therefore, are worthy of being assessed in order to increase their applications. In the context of prevention, photocatalysis allows us, for instance, to conduct selective partial oxidations at mild temperature and pressure conditions. Photocatalyzed processes can also be applied to correct an environmental problem in the air and/or water. Therefore, this Special Issue, “Photo-Catalyzed Processes for a Cleaner Environment”, is dedicated to addressing the following topics:

  • Photocatalyzed advanced oxidation processes, i.e., photocatalysis, photo-Fenton, and photo-electrocatalysis;
  • Photocatalyzed reduction processes, i.e., CO2 photocatalyzed or photo-electrocatalyzed conversion;
  • Selective photocatalyzed or photo-electrocatalyzed oxidations;
  • Solar fuels;
  • Integration of photocatalyzed processes with others (adsorption, biological, ozone, electrochemical, and persulfate) for pollutant removal.

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.

Since the conventional processes employed in most wastewater treatment plants (WWTPs) worldwide are not designed to entirely remove or oxidize emerging pollutants, which, due to their incidence and persistence, can cause damage to both the environment and human health, several options for their degradation and removal have emerged. Coupling the advanced Fenton oxidation process as a polishing or tertiary wastewater treatment alternative within conventional WWTP processes stands out among the treatment options. Therefore, the main objective of this research was to evaluate, at the laboratory level, the ability of the advanced Fenton oxidation process to oxidize triclosan, ibuprofen, DEET (N, N-diethyl-meta-toluamide), carbamazepine, caffeine, and acesulfame-K, which represent several groups of emerging pollutants in real wastewater from the second settling tank of a municipal WWTP. The compound used as a catalyst (Fe2+) supplier in the advanced Fenton oxidation process was ferrous sulfate heptahydrate (FeSO4•7H2O). The results obtained upon application showed that the advanced Fenton oxidation process could simultaneously oxidize and remove practically the total concentration of the above-mentioned emerging pollutants, except for DEET (85.21%), in conjunction with the chemical oxygen demand (COD), total suspended solids (TSS), and fecal coliforms (FC, pathogen group) in the effluent generated by the advanced Fenton oxidation process.
