Special Issue Information

Dear Collleagues,

The development of bifunctional materials that are able to catalyze oxygen-related reactions, i.e., the oxygen reduction (ORR) and the oxygen evolution (OER) reaction, is still a challenge for the progress of energy conversion and storage devices such as metal–air batteries or unitized regenerative fuel cells. These devices represent a promising future for a clean and sustainable conversion and storage of energy. Regenerative fuel cells produce H2 and O2 when acting as water electrolysers and provide electricity when acting as fuel cells fed with H2. On the other hand, metal–air batteries are envisaged as next-generation batteries, with extraordinary high energy densities, being promising systems for portable, mobile or stationary applications. Oxygen electrodes can be very lightweight and thin because the active material, oxygen, does not need to be stored inside the cell. However, these electrodes are restricted by the poor reaction kinetics and low activity of many catalysts towards the oxygen evolution and reduction reactions.

In addition, it is a challenge to maintain the chemical and mechanical stability of the catalyst and supporting materials at oxidizing currents under the strong alkaline conditions commonly used, and under gas evolution. This Special Issue aims to cover the most recent advances and developments regarding bifunctional catalysts as oxygen electrodes.

Oxygen reduction reaction (ORR) has attracted considerable attention for clean energy conversion technologies to reduce traditional fossil fuel consumption and greenhouse gas emissions. Although platinum (Pt) metal is currently used as an electrocatalyst to accelerate sluggish ORR kinetics, the scarce resource and high cost still restrict its further scale-up applications. In this regard, biomass-derived carbon electrocatalysts have been widely adopted for ORR electrocatalysis in recent years owing to their tunable physical/chemical properties and cost-effective precursors. In this minireview, recent advances of the optimization strategies in biomass-derived carbon electrocatalysts towards ORR have been summarized, mainly focusing on the optimization of pore structure and active site. Besides, some current challenges and future perspectives of biomass-derived carbon as high-performance electrocatalysts for ORR have been also discussed in detail. Hopefully, this minireview will afford a guideline for better design of biomass-derived carbon electrocatalysts for ORR-related applications. Full article
