Recent Developments in Photocatalytic Hydrogen Production

Dear Colleagues,

Hydrogen continues to gain traction as a versatile energy carrier with the potential to decarbonize various sectors due to its high energy density (120 MJ/kg) and green and pollution-free combustion products. The International Energy Agency’s Global Hydrogen Review 2024 indicated that global hydrogen demand reached 97 Mt in 2023, an increase of 2.5% compared to 2022. Despite the challenges, significant investments and technological advances are driving progress in this area. The technologies used for hydrogen production can be broadly classified into thermal, electrochemical, biological, and photonic (light-driven) methods. In particular, photocatalytic techniques have garnered widespread interest, and photocatalytic hydrogen production is advancing rapidly thanks to innovations in materials science.

For this Special Issue, authors are invited to submit original research articles or reviews that emphasize the potential for scalable and sustainable hydrogen production.

Potential topics include, but are not limited to, the following:

• Photocatalytic water splitting.
• The photoreforming of organics.
• Photothermal water splitting.
• Photoelectrochemical water splitting.
• Hybrid approaches.

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.
