Challenges in applying highly active Pt-based nanostructured catalysts for oxygen reduction reactions to fuel cell vehicles

Kensaku Kodama et al.

Summary: Progress has been made in the development of Pt-based nanocatalysts for the oxygen reduction reaction over the past 30 years, with some now in commercial production for PEFCs. However, further improvements in catalytic activity are needed. State-of-the-art catalysts have potential to enhance energy conversion efficiencies and reduce platinum usage in PEFCs, but technical challenges remain for their application in fuel cell vehicles, such as high power density, practical durability, and efficiency.

Self-Validated Machine Learning Study of Graphdiyne-Based Dual Atomic Catalyst

Mingzi Sun et al.

Summary: Although the current progress of atomic catalysts is mainly limited to single atomic catalysts (SAC), with few successful cases of dual atomic catalysts (DAC), addressing challenges in thermodynamic stability and optimal metal combinations is crucial. Theoretical investigations on GDY-based DAC reveal that introducing selected lanthanide metals improves stability and electroactivity, with f-d orbital coupling identified as a key factor in modulating the d-band center for enhanced stability. These findings offer new insights into DAC and pave the way for advancements in atomic catalyst research.

Dynamic Behavior of Single-Atom Catalysts in Electrocatalysis: Identification of Cu-N-3 as an Active Site for the Oxygen Reduction Reaction

Ji Yang et al.

Summary: Atomically dispersed Cu-N-C single-atom catalysts with Cu2+-N-4 structure exhibit comparable activity and superior durability to Pt/C in the electrochemical reduction of oxygen. The dynamic evolution of Cu-N-4 to Cu-N-3 and further to HO-Cu-N-2 under ORR conditions is identified, with the low-coordinated Cu+-N-3 being determined as the real active site. The findings may guide the design of more efficient low-cost catalysts.

Pt-Co@Pt Octahedral Nanocrystals: Enhancing Their Activity and Durability toward Oxygen Reduction with an Intermetallic Core and an Ultrathin Shell

Minghao Xie et al.

Summary: In this study, Pt-Co@Pt octahedral nanocrystals were successfully synthesized with an intermetallic Pt-Co core and an ultrathin Pt shell dominated by {111} facets on the surface.
