Abstract

We present a surfactant-free approach for synthesizing size-dependent carbon supported Pt nanoparticles with mean sizes ranging from 4.8 to 1.7 nm by increasing ratios of CO/Ar. In this work, gas stabilizer exhibits the originality on the design of the supported size-controllable clusters.
