Special Issue Information
Dear Colleagues,
The production of green hydrogen through water electrolysis powered by renewable energy sources constitutes one of the most promising solutions to tackle climate change. With recent advances in solar and wind energy, the price of electricity is drastically decreasing, even achieving zero cost when the electrical grid cannot cope with electricity production. In order to lower the costs of water electrolysis, research into novel electrocatalysts based on earth-abundant elements is fundamental. These need to be applied to both the oxygen-evolving reaction (OER) and the hydrogen-evolving reaction (HER). Targeted electrocatalysts need to be active and stable over different pH ranges, depending on the type of electrolyzer to be incorporated in. Moreover, they should be able to maintain their activity in the presence of foreign ions or molecules, so that the purification requirements for long-term operation are minimized.
This Special Issue aims to cover recent research and developments in the synthesis of highly-stable and active electrocatalysts for water splitting, both for OER and HER. For the advancement in the field, we encourage authors to contribute to this issue with electrocatalysts based on both molecular and materials systems, since detailed understanding of the mechanisms of the reaction is crucial for the design and preparation of novel electrocatalysts. In addition, details of advanced characterization of electrocatalysts, computational studies, incorporation in flow electrochemical cells and potential scale-up of electrolyzers are important subjects in this issue.

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.
