Air and Water Purification Processes through Photocatalysis: Scale Up Perspectives

Dear Colleagues,

In recent years, photocatalytic processes have been profusely proposed for the decontamination of air and water from organic and inorganic pollutants, as well as for disinfection. The scientific interest in this topic is ever-growing, as evidenced by the number of publications, citations, and international conferences dedicated to this topic.

Realistically, the fundamental knowledge of these processes and their potential has increased enormously, and the scientific community is now ready to evaluate the translation of these concepts into the scale-up development toward practical and industrial application. We are now in the challenging period in which laboratory investigations of these promising technologies should be the sound basis for the design of commercial plants. Several parameters must be analyzed in this context, including reactor configuration (batch or continuous), irradiation sources (wavelength and power), the stability of the photocatalysts, byproduct formation, the scale-up of photocatalyst synthesis procedures (cost and availability of raw materials, development of the preparation procedure toward higher productivity), the impact on the scale-up of other synergetic technologies (ultrasound, ozone, Fenton, chemicals addition), etc.

The aim of this Special Issue is to collect papers that report research focused on any possible development of photocatalytic processes in air and water remediation.  

Both theoretical and applied studies (focusing on investigating catalysts in realistic environments and improving stability) are of interest. Additionally relevant are reports that detail new possible plant and reactor configuration and simulation studies. The hope is to compile a set of manuscripts that contribute to the development of the state-of-the-art to transform laboratory studies in final concrete applications, following the principle “our recent studies, your future technologies”.

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.
