Special Issue Information

Dear Collleagues,

The development of bifunctional materials that are able to catalyze oxygen-related reactions, i.e., the oxygen reduction (ORR) and the oxygen evolution (OER) reaction, is still a challenge for the progress of energy conversion and storage devices such as metal–air batteries or unitized regenerative fuel cells. These devices represent a promising future for a clean and sustainable conversion and storage of energy. Regenerative fuel cells produce H2 and O2 when acting as water electrolysers and provide electricity when acting as fuel cells fed with H2. On the other hand, metal–air batteries are envisaged as next-generation batteries, with extraordinary high energy densities, being promising systems for portable, mobile or stationary applications. Oxygen electrodes can be very lightweight and thin because the active material, oxygen, does not need to be stored inside the cell. However, these electrodes are restricted by the poor reaction kinetics and low activity of many catalysts towards the oxygen evolution and reduction reactions.

In addition, it is a challenge to maintain the chemical and mechanical stability of the catalyst and supporting materials at oxidizing currents under the strong alkaline conditions commonly used, and under gas evolution. This Special Issue aims to cover the most recent advances and developments regarding bifunctional catalysts as oxygen electrodes.

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 papers will be 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 1600 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.
