Special Issue Information

Dear Colleagues,

Electrochemical devices such as metal–air batteries, water-splitting cells, and alkaline fuel cells present clean, green, and renewable energy technologies, and they have been widely examined in recent decades. Namely, the crucial impacts of their high performances are electrocatalysts for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). The state-of-the-art electrocatalysts for all three reactions are noble metal-based catalysts where Pt/C is the best electrocatalyst for HER and ORR and IrO2 and RuO2 for OER. On the other hand, the scarcity and high cost of these electrocatalysts present a huge disadvantage in their application in renewable energy technologies. Because of this, it is fundamentally important to make and explore low-cost electrocatalysts with high activity and stability for HER, OER, and ORR.

This Special Issue, entitled  ̎Advanced Electrocatalysts for Clean and Renewable Energy Conversion and Storage Processes ̎, will focus on novel, easy synthesis and low-cost electrocatalysts with high activity for HER, and/or ORR, and/or OER in alkaline media.

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. Processes 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 2400 CHF (Swiss Francs).

Developing bifunctional oxygen electrode materials with superior activity for oxygen reduction (ORR) and oxygen evolution (OER) reactions is essential for advancing regenerative fuel cell and rechargeable metal–air battery technologies. This present work deals with the synthesis and characterization of electrocatalysts containing Pt and Ni nanoparticles supported on nitrogen-doped mixed metal oxides (Mn2O3-NiO) and the systematic evaluation of their bifunctional ORR/OER performance in an alkaline medium. These electrocatalysts have been successfully synthesized by a simple and fast microwave method. PtNi/Mn2O3-NiO-N with a binary metal oxide-to-N ratio of 1:2 demonstrated the best performance among the studied materials regarding bifunctional electrocatalytic activity (∆E = 0.96 V) and robust stability.
