Application of Catalysis in Wastewater Treatment

Dear Colleagues,

The growing demand for clean water and the increasing contamination of water resources by toxic contaminants have motivated innovations in water and wastewater treatment and environmental remediation areas for the removal of recalcitrant contaminants. Some biological, chemical and physical techniques are used to acquire high-quality effluents in wastewater treatment. Nevertheless, these techniques have some restrictions related to the treatment efficiency, inactivation by toxic pollutants, high energy and cost requirements, production of secondary sludge, etc. Catalytic treatment of polluted water is considered a promising alternative for the removal of aqueous organic contaminants. Heterogeneous catalytic technologies involving the production of different reactive species have recently emerged with capabilities to convert organic contaminants in aqueous media. The contaminants falling under this category include detergents, pharmaceuticals, pesticides, microplastics, dyes, personal care products, plasticizers, illicit drugs, disinfection byproducts, endocrine-disrupting compounds, artificial sweeteners, estrogens, anticorrosives, etc. This Special Issue will mainly consider novel research works and reviews focusing on the recent trends and progress in the development of heterogeneous catalytic processes for water treatment through modifications of system designs and fabrication of novel materials. Different catalytic technologies including photo/electrochemical techniques, photocatalysis, sonocatalysis, Fenton and Fenton-like processes, catalytic ozonation, catalysis-membrane-integrated processes, self-purifying methods with reduced resource and energy consumption, persulfate activation, novel activation methods, modeling and simulation, etc. are covered as effective techniques for the removal of pollutants in this Special Issue. Investigations on the synthesis and use of advanced nanomaterials and economic analyses of developing techniques for environmental remediation are also welcomed.

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.
