Carbon-based Catalysts for Electrochemical Energy Conversion

Dear Colleagues,

In the last decade, we have been witnessing the unprecedented advances in electrochemical power sources. This development has established a vast market of electrochemical devices and materials with the industry demanding for sustainable and economically feasible technologies of production. A typical electrochemical cell uses carbon-based catalysts to speed-up electrode reactions. The scarce and limited resources for efficient PGM-based electrocatalysts stimulated incremental studies of PGM-free or low-PGM catalysts. Despite of multiple studies, the nature of catalytically active sites remains controversial, while this knowledge is of paramount importance for designing an efficient and low-cost catalyst for the large-scale production of low temperature fuel cells.

This Special Issue is thought to gather under a single cover the scientific contributions on synthesis of novel PGM-free and low-PGM carbon-based electrocatalysts. Their electrochemical activity is expected to be tested in various media and in different reactions. Special emphasis is likely to be given to the nature of active sites involved, to the analysis of reaction mechanism and kinetics. Characterization by all relevant methods including in-situ and operando is encouraged. Fundamental observations and applicability are valuable findings foreseen for original research papers, while short reviews may provide an in-depth inquiry or draw the upcoming trends.

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.
