Special Issue Information

Dear Colleagues,

In the global challenge to reduce the use of fossil fuels and the impact of the anthropogenic activities, novel and sustainable technologies for energy production and conversion are needed, such as fuel cells and lithium air batteries. As is well known, one of the key factors in these systems is the sluggish kinetic of the Oxygen Reduction Reaction that occurs at the cathode. Thus, the development of novel and efficient catalysts able to directly reduce the oxygen molecule, through the four-electron pathways, is a fundamental step for the large-scale diffusion of such energy systems.

Of great interest is the finetuning of the physicochemical properties, which are strictly related to the catalysts’ properties and in particular to the electrochemical performances (catalytic activity, efficiency and long-term stability). This Special Issue welcomes papers presenting the development of novel catalysts for oxygen reduction applications with special attention to advanced synthesis approaches, environmentally friendly processes, cost efficiency, and fundamental understanding of structure–activity relationships and ORR performances.

It is my pleasure to invite you to contribute to enhancing the quality of this Special 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).

Catalysts for the oxygen reduction reaction (ORR) in PEM fuel cells are commonly constituted of Pt-based nanoparticles and a carbon support originating from fossil resources. In order to employ a more sustainable carbon support, activated sawdust was chosen in this study. This was firstly steam-activated at 750 °C and then thermally treated at elevated temperatures up to 2800 °C and reducing conditions at 1100 °C. Various physical characterization methods were applied to systematically relate treatment parameters to surface and structural properties of the carbon material. Deposition of small Pt nanoparticles on the biochar-based supports yielded in ORR active catalysts which were analyzed by thin-film rotating disc electrode measurements. The activity and stability towards the ORR of these novel catalysts was compared to a commercial raw oil-based Pt/C and the influence of support modification on the ORR performance was discussed.
