Special Issue Information

Dear Colleagues,

Nowadays, biological treatment is considered to be among the best available technologies for wastewater treatment because of its low operating and capital costs. However, conventional biological treatments have long retention times and usually fail to degrade high-strength wastewater or bio-refractory compounds. In such cases, available technologies to deal with these kinds of contaminants include the use of the so-called advanced oxidation processes (AOPs). Among AOPs, heterogeneous/homogeneous catalytic/photocatalytic oxidation processes have been proved to be an efficient tool for the degradation of complex organic contaminants. However, AOPs have disadvantages over biological processes as they require continuous energy and/or chemical inputs that are significantly higher than those required for biological processes. In this sense, in recent years the attention of research has focused on AOPs that can be driven by solar light as photo-Fenton and heterogeneous photocatalysis. Therefore, using the strengths of AOPs and biodegradation in a combined technology could be proposed as an appropriate treatment strategy for recalcitrant wastewaters to minimize installation and operation costs.

Thus, the Special Issue will be focused on AOPs (catalytic/photocatalytic processes) used as pre- and/or post-treatment of biological systems, highlighting the following topics:

(i) novel catalysts for catalytic/photocatalytic AOPs;
(ii) novel biological treatments;
(iii) the degradation of contaminants of emerging concern, priority pollutants, and/or real wastewaters;
(iv) mechanisms and kinetics;
(v) pilot-scale studies and industrial scale up approaches.

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 papers will be 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 1800 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.
