Summary: Platinum-based ordered intermetallic compounds are promising low-Pt catalysts for the oxygen reduction reaction (ORR) in fuel cells. The synthesis of ordered intermetallic catalysts usually requires high-temperature annealing, which leads to sintering of catalysts and reduced activity.

The core/shell structure avoids diffusion of Cu atoms to Pt nanoparticles, resulting in higher ordering degrees of PtCu nanoparticles. The catalysts prepared by this strategy exhibit higher mass and specific activity compared to the traditional wet-impregnation method. A positive correlation between ORR activity and the ordering degree of PtCu nanoparticles is identified.

Intermetallic FePt@PtBi Core-Shell Nanoparticles for Oxygen Reduction Electrocatalysis

Jingyu Guan et al.

Summary: The development of platinum-based oxygen reduction reaction electrocatalysts with good resistance to poisoning is crucial for practical fuel cell applications. A surface-engineering approach using alloy PtBi shells to prepare nanostructured Pt alloys showed significantly improved ORR performance compared to benchmark Pt/C, with enhanced tolerance to methanol and carbon monoxide. The observed enhancement in performance is attributed to increased compressive strain and charge displacement via Pt-Bi bonding.

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. These nanocrystals showed significantly improved catalytic performance towards the oxygen reduction reaction compared to a commercial Pt/C catalyst, with a mass activity 13.4 times higher and a specific activity 29.5 times higher. Importantly, the mass activity of the nanocrystals only decreased by 21% after 30,000 cycles of accelerated durability testing, indicating their outstanding potential as catalysts for ORR and related reactions.

Perspective on intermetallics towards efficient electrocatalytic water-splitting

Carsten Walter et al.

Summary: Intermetallic compounds show attractive electronic, physical, and chemical properties, making them ideal materials for electrocatalytic applications. However, their widespread use is often hindered by complex and energy-intensive processes, leading to larger particles and decreased surface areas. Alternative synthetic strategies are being explored to achieve high performance and stable electrode materials.
