Engineering dual metal single-atom sites with the nitrogen-coordinated nonprecious catalyst for oxygen reduction reaction (ORR) in acidic electrolyte

Hussein Gharibi et al.

Summary: In this study, an electrocatalyst composed of dual metal single-atom sites attached to nitrogen-doped porous carbon was developed using a host-guest design. Co-Fe SAs/NC showed remarkable oxygen reduction reaction (ORR) performances compared to other samples, with higher onset potential and limiting current density values, and greater stability in durability measurements. This suggests that Co-Fe SAs/NC could be a promising ORR catalyst for use in fuel cells to improve ORR kinetics and durability.

Feng Liu et al.

Summary: A novel polydopamine-metal complex-assisted pyrolysis strategy was used to produce catalysts with hierarchically porous carbon support and highly exposed dense-FeN4 sites, leading to significantly enhanced performance for oxygen reduction reaction (ORR) and superior power densities in proton exchange membrane fuel cells (PEMFCs). The quantitative relationship between the active site activity and ORR performance was established, highlighting the dominating role of FeN4 site density in the observed excellent PEMFC performance. This work provides a useful guidance for the design and development of novel highly-efficient single-atomic catalysts for renewable energy applications.

Ligang Ma et al.

Summary: The interfacial atomic configuration between dual-metal active species and nitrogen-carbon substrates is crucial for enhancing the intrinsic activity of catalysts towards the oxygen reduction reaction (ORR). By incorporating atomically dispersed dual Fe centers into N-doped carbon nanotubes, a high intrinsic activity ORR catalyst was developed with exceptional activity surpassing state-of-the-art Pt/C. This catalyst not only exhibits superior kinetic properties but also enables primary Zn-air batteries to achieve high power densities and sufficient cycling stability.

Introduction of a new active and stable cathode catalyst based on bimetal-organic frameworks/ PPy-sheet for alkaline direct ethanol fuel cell

Seyed Mohammad Seyed Bagheri et al.

Summary: For the first time, polypyrrole with a sheet-like structure was synthesized using a highly efficient and simple chemical reaction process. A new composite material, BMZIF@PPy, was synthesized by growing bimetallic zeolitic imidazolate frameworks on the polypyrrole sheets. The BMZIF@PPy composite was then heat-treated at different temperatures to create oxygen reduction reaction (ORR) electrocatalysts. Through electrochemical measurements, the ORR properties of the Co/Zn-NC@PPy-800 catalyst were investigated in both acidic and alkaline media. The Co/Zn-NC@PPy-800 catalyst exhibited good activity and stability in alkaline media, making it suitable as a cathode in alkaline direct ethanol fuel cells. The maximum power of the Co/Zn-NC@PPy-800 cathode catalyst was 77% higher than that of the commercial Pt/C electrocatalyst.

Hongguan Li et al.

Summary: This study reveals the significant impact of the cooperative interplay between charge itineration and spin-polarization of electrons on catalytic behavior through density functional theory calculations. The Fe-Ni atomic pair is reported as a superior bifunctional catalyst for high performance ORR and OER, with a very small potential difference (Delta E) of 0.691 V. The coexistence of Fe 3d itinerant charge and moderate spin polarization is responsible for the superior functional catalytic activity for the Fe-Ni atomic pairs.
