Abstract

The influence of particle size on the oxygen reduction reaction (ORR) activity of Pt was examined in three different electrolytes: two acidic solutions, with varying anionic adsorption strength (HClO(4) unsupported Pt black particles (~30 nm) > high surface area (HSA) carbon supported Pt nanoparticl...
