Abstract:
High oxygen reduction activity has been for many years considered as the key to many energy applications. Herein, by combining theory and experiment we fabricate Pt nanoparticles with optimal size for the efficient oxygen reduction reaction (ORR) in proton‐exchange‐membrane fuel cells. Optimal nanoparticle sizes are predicted near ~1, 2, and 3 nm by computational screening. To corroborate our computational results, we have addressed the challenge of ~1 nm sized Pt nanoparticle synthesis with a m...     »
