Commemorative Special Issue for Prof. Dr. Dion Dionysiou

Dear Colleagues,

With heavy heart, we announce a Special Issue dedicated to the memory of Professor Dionysios (Dion) Dionysiou, who passed away at 57 years old on November 20th, 2023. This Special Issue will honor his remarkable contributions to catalysis, environmental engineering, and water pollution treatment.

Throughout his illustrious career, Dion made significant strides in advancing our understanding of radical generation and their application in degrading organic water contaminants. His groundbreaking research, characterized by over 600 publications cited more than 68,000 times, has left an indelible mark on the field. As a tribute to Dion's legacy, this Special Issue will focus on topics closely aligned with his areas of expertise. We invite researchers to submit original research articles and reviews covering the following themes, but are not limited to:

• Radical generation and their applications in environmental catalysis;
• Novel catalytic approaches for water pollution monitoring and treatment;
• Catalytic Chemical oxidation and reduction technologies;
• UV and biological processes for water catalytic treatment;
• Catalytic Oxidation and Reduction Technologies;
• Electrocatalytic and Electrochemical Oxidation and Reduction Technologies;
• Fenton and Photo-Fenton Catalytic Oxidation Processes;
• UV Based Catalytic Oxidation processes.

In addition to honoring Dion's pioneering work, this Special Issue seeks to inspire further innovation and collaboration in addressing pressing environmental challenges. We welcome contributions from colleagues, collaborators, and admirers of Dion's work. We also welcome contributions from researchers attending the 28th International Conference on Advanced Oxidation Technologies for Treatment of Water, Air, and Soil.

We extend our condolences to Dion's family, friends, colleagues, and the broader catalysis community. May this Special Issue serve as a fitting tribute to his enduring legacy and outstanding impact on environmental science and engineering.

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.
