Photocatalytic Properties and Kinetics of Materials

Dear Colleagues,

Photocatalytic materials have been the subject of extensive studies in the last decade due to their unique properties such as promoted catalysis, adsorption surface, and high reactivity in mild conditions. This Special Issue is devoted to exploring and highlighting the relationships between the structure, morphological and optical properties, and the features of photocatalysts and photoactivity.

The synthetic procedures, including doping, semiconductor coupling, and surface coating, can noticeably affect the physicochemical properties of semiconductors. Innovative photocatalysts implemented as layered materials; nanostructures; size- or shape-tuned nanoparticles; micro-, meso-, and macro-structured catalysts; as well as composites with other functional materials are included. Chemical, physical, electrical, magnetic, and optical characterization will help identify correlations with the photocatalytic performance of the advanced materials.

Photocatalytic materials are able to promote photoreactions and their performance depends on the kind of molecules, level of concentration, temperature, solution pH, photocatalyst dosage, presence of other organic and inorganic compounds, and kind and intensity of light. Understanding and modeling kinetics are essential for the optimization and implementation of photocatalytic processes. Fundamental investigation on photocatalytic kinetics of semiconductors photocatalysts may validate the proposed reaction mechanism and can offer a mathematical law as function of operative parameters.

In this Special Issue, frontier researchers and colleagues are invited to present original papers and review articles involving (without being limited to) the topics listed below:

• materials for photocatalytic water and wastewater treatment
• materials for sustainable photocatalytic synthesis
• materials for photocatalysis under visible light
• materials for CO₂ photoreduction
• materials for air purification
• materials for bacterial photoinactivation

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. Materials 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.
