Key Points

Discontinuity in the oxygen reduction reaction was observed at a critical scale of ~1.0 nm.
Synthesis of surfactant-free platinum nanoparticles at ~1.0 nm led to notable changes in catalytic behavior.
Controlled solution plasma method was utilized for creating monodisperse nanoparticles to investigate size effects.
These findings suggest the potential for optimizing nanoparticle size to enhance catalytic efficiency in applied settings.

Abstract

Quantum-induced discontinuity in the oxygen reduction reaction (ORR) catalyzed by Pt nanoparticles (NPs) occurs at the ~1.0 nm scale. Using a controlled solution plasma method, we synthesized monodisperse, surfactant-free ~1.0-nm...
