%X <p>Composite carbon–platinum thin-films of nano-crystalline graphitic carbon decorated with uniformly-dispersed 2–4 nm Pt nano-particles have been synthesized from a solid organic precursor by a one-step microwave plasma chemical vapor deposition (MPCVD). The fast Ar-plasma discharge and the presence of microwave radiation accelerate the formation of sites suitable for <em>in situ</em> heterogeneous nucleation, and consequently, the fine dispersion of metal in the carbonaceous matrix. The electrochemical response of the 2 μm C/Pt thin-film electrode displays electrochemical activity, which is attributed to the high ca. 18 m<sup>2</sup>/g effective surface area of Pt nano-particles.</p>
