Advanced Catalysts for Water Electrolysis

Dear Colleagues,

The development of highly efficient, durable, and cost-effective water electrolysis technologies is crucial for a future sustainable hydrogen economy. The core of this green hydrogen production pathway lies in the electrocatalysts that drive two pivotal half-reactions: the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). The intrinsic activity and stability of these catalysts primarily determine the overall energy efficiency and economic viability of electrolysis systems. Therefore, this Special Issue is dedicated to the latest breakthroughs and cutting-edge research in the design, synthesis, characterization, and application of advanced catalysts for water electrolysis. We welcome contributions focusing on innovative strategies to overcome the kinetic limitations and high overpotentials, especially those associated with the OER. All types of articles, including original research articles, communications, and brief research reports, are welcome. Perspectives and reviews on the progress and challenges of advanced catalysts for water electrolysis are also highly appreciated.

Topics of interest include, but are not limited to, the following:

• Precious metal catalysts (e.g., Pt-based catalysts, RuO₂, and IrO₂);
• Novel non-precious metal catalysts (e.g., transition metal phosphides, sulfides, selenides, oxides, and hydroxides);
• Single-atom catalysts and tailored nanoscale architectures;
• Fundamental mechanistic studies and operando characterization of active sites;
• Stability enhancement and degradation mechanism analysis;
• Catalysts for various electrolyzer technologies (AEM, PEM, and SOEC).

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.
