Special Issue Information
Dear Colleagues,
The consumption of fossil fuel resources and the urgent quest to decrease carbon emissions have intensified worldwide efforts toward carbon-neutral and sustainable energy technologies. Therefore, photocatalytic water splitting has emerged as a potential strategy for generating green hydrogen (H2) via directly transforming solar energy into chemical energy by employing plentiful sunlight and water. Despite the significant efforts made in the construction of photocatalysts and system design, challenges such as low activity, poor visible-light absorption, quick charge recombination, and long-term stability hinder practical applications still remain. Thus, advanced, stable, and highly efficient photocatalytic materials and mechanisms are crucial to elevate the progress and scaling-up of solar H2 generation technologies.
This Special Issue aims to publish original research and review articles related to “Photocatalytic Water Splitting: State of the Art and Future Challenges.” Topics will include, but are not limited to, the following research areas:
- Photocatalysis;
- Photocatalytic water splitting (Overall, H2 and O2 evolution reactions);
- Photocatalyst design and engineering.
I look forward to receiving your valuable contributions.
Best regards
Dr. Ikram Ullah
Guest Editor
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. 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 2200 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.
