Special Issue Information
Dear Colleagues,
To date, transition metal-based electrocatalysts with low-price and adequate reserves have stimulated extensive efforts on green and renewable energy technologies, especially for fuel cells. As the heart of the fuel cell, the oxygen reduction reaction (ORR) is of paramount importance, while platinum-based noble metal electrocatalysts are known as highly efficiently ORR electrocatalysts for fuel cells. However, the high cost and limited reserve of Pt preclude commercial applications. In order to further reduce or even eliminate the usage of Pt, great efforts have been made on the development of non-noble metal electrocatalysts (NNMEs). Today, NNMEs are regarded as the most promising electrocatalysts as alternatives for Pt-based electrocatalysts for the ORR, though the relatively low density of active sites in NNMEs hinders their research and development. Thus, from the aspects of synthesis method and mechanism research, it is crucial to enhance the effective exposure of the active sites in NNMEs. As a result, iron- and/or cobalt-based NNMEs are highly effective for ORR in alkaline and acidic solution. This Special Issue aims to cover recent progress and trends in designing, synthesizing, characterizing, and evaluating advanced NNMEs for both alkaline and acidic solution.

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.
