Reconstructing the Coordination Environment of Platinum Single-Atom Active Sites for Boosting Oxygen Reduction Reaction

Jing Liu et al.

Summary: Efficient platinum single-atom (Pt-1) catalysts are sought after for reducing the costs of polymer electrolyte membrane (PEM) fuel cells. In this study, a Pt-based electrocatalyst was prepared by hydrothermal ethanol reduction method with high selectivity for the oxygen reduction pathway. Further reconstruction of the coordination environment led to the formation of highly efficient platinum single-atom active sites for oxygen reduction. The obtained catalyst demonstrated excellent performance and stability, outperforming commercial Pt/C by 8.7 times in mass activity at a cell voltage of 0.9 V.

Tailoring Acidic Oxygen Reduction Selectivity on Single-Atom Catalysts via Modification of First and Second Coordination Spheres

Cheng Tang et al.

Summary: This study demonstrates that the molecular-level local structure, including first and second coordination spheres, plays a critical role in determining the selectivity of catalytic reactions. By modifying the first and second coordination spheres of Co-SACs, it is possible to tailor the oxygen reduction reaction selectivity. The unique selectivity change originates from the structure-dependent shift of active sites, leading to improved activity and selectivity for acidic H2O2 electrosynthesis.

Local Coordination and Reactivity of a Pt Single-Atom Catalyst as Probed by Spectroelectrochemical and Computational Approaches

Kun Jiang et al.

Summary: The study investigates the local coordination environment around Pt sites in single-atom catalysts, revealing two different Pt coordination structures with varying CO binding strengths. By comparing the COad electrooxidation mechanism, it is found that the CO oxidation process on the Pt-N-C site differs from that on the bulk Pt surface.
