Special Issue Information
Dear Colleagues,
The electrocatalytic oxygen evolution reaction (OER) and oxygen reduction reaction (ORR), known as oxygen electrocatalysis, play a key role in sustainable energy conversion and storage devices, such as unitized regenerative fuel cells and rechargeable metal–air batteries, which has attracted the attention of many researchers in the past few decades. In fuel cells and metal–air batteries, the cathode of the battery transports oxygen ions and provides a site for the oxygen reduction reaction. However, due to a complex four proton-coupled electron transfer process, the sluggish kinetics still render OER/ORR catalysts less efficient for the practical efficiency of these sustainable electrochemical devices. Moreover, the complexity of the catalyst–electrolyte interface makes a comprehensive understanding of the intrinsic OER/ORR mechanisms challenging. Recently, for the OER and ORR, the best-performing electrocatalysts remain dominated by precious metals, such as, Ir and Pt. Therefore, the development of a highly efficient catalytic system is the key to improving device performance and reducing its manufacturing cost to meet the needs of next-generation battery commercialization.
This Special Issue entitled “OER/ORR electrocatalysis” will focus on the state of the art and outlooks for oxygen electrocatalysis. Submissions in the form of original research papers and review articles in the areas of designing novel OER/ORR electrocatalysts, developing new electrocatalytic systems, and finding new mechanisms for oxygen electrocatalysis are all welcome.

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 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.
