Dear Colleagues,

Photocatalysis technology has emerged as a promising solution for addressing various air pollutants, ranging from CO₂ conversion and NO_x oxidation to VOCs degradation and indoor air pollutant removal. By harnessing the power of photocatalysts such as TiO₂, MnO₂, and conjugated polymers, photon energy is absorbed and transformed into valuable chemical energy. Extensive research has been conducted to enhance the photon utility of photocatalysis through techniques such as modifying physical and chemical properties, heteroatom doping, creating heterojunctions, and optimizing reactor designs. Alongside treatment efficiencies, factors such as photocatalyst lifespan, tolerance to toxic components, and the selectivity of desired products are pivotal in evaluating the overall quality of photocatalysts. In particular, minimizing by-products, especially aromatic compounds, during VOCs degradation is of utmost importance.

The Special Issue aims to cover the in-depth exploration of recent progress and advancements in the field of photocatalysis. The scope of the Special Issue encompasses, but is not limited to, the preparation and characterization of innovative materials, the application of photocatalysis in tackling air pollutants, and the theoretical study of reaction mechanisms and kinetics.

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.
