The Pt3Rh/C nanoalloy demonstrates exceptional performance with a minimum overpotential of 0.60 V for both ORR and OER.
This enhancement leads to improved oxygen reduction and evolution efficiency, achieving a capacity of 2000 mAh g−1.
The innovative use of nanoporous carbon provides optimal storage and transport channels for Li+ and O2.
Incorporating bimetallic Pt3Rh architecture optimizes electron transfer and catalytic efficiency for Li-O2 battery applications.
