Special Issue Information
Dear Colleagues,
Photocatalysis has attracted a great deal of interest because of the ability of photocatalysts to harvest sunlight and drive a variety of chemical reactions. Photocatalytic processes have the potential to solve a variety of environmental problems, ranging from removing pollutants from water and air, to capturing carbon dioxide and converting it to useful chemical feedstocks, and producing hydrogen—a “clean” fuel—from water. All of these processes rely on efficient and selective photocatalysts. One of the earliest photocatalysts, titanium dioxide, is still one of the most important photocatalyst materials, offering high efficiency, low cost, and the ability to tune its morphology. However, it has significant weaknesses, such as poor visible light absorption and detrimental charge recombination. The search for alternative improved photocatalysts has led to a huge amount of research into novel photocatalyst materials, such as mixed oxides, graphitic carbon nitride, polymeric and molecular photocatalysts, as well as modifications of their electronic and optical properties by doping and by control of their morphology. Composite photocatalyst systems, e.g., heterojunctions of metal oxides with efficient light absorbers such as chalcogenides, graphene and carbon nanotubes, and molecular photosensitizers, offer improved light absorption and charge separation ability and therefore result in high photocatalytic efficiencies.
This Special Issue covers experimental and theoretical research on cutting-edge photocatalysts, such as:
- Novel photocatalyst materials;
- Doping of photocatalyst materials;
- Control of photocatalysts’ morphology;
- Photocatalytic heterojunctions, e.g., Z-schemes;
- Photocatalyst–molecular sensitizer systems;
- Visible-light photocatalysis.

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.
