Abstract

Boron-doped polycrystalline diamond is being investigated as an advanced electrocatalyst support material in comparison with commonly used sp² carbon materials. This new support material exhibits excellent morphological and microstructural stability (>2 h) at high current density (0.1 A/cm ²) and temperature (>150°C); stability that is superior to conventional sp²-bohded carbon supports. Metal/diamond composite electrodes were formed Using both microcrystalline and nanocrystalline thin-films. The electrocatalytic (Pt) metal was deposited via a pulsed galvanostatic method, which produced metal particles of relative small nominal diameter and high number density, at least compared to previous work with constant potential and current deposition. The metal particles can be stabilized into the diamond surface by a secondary diamond growth of short duration. The catalytic activity of the supported Pt particles was probed using the oxygen reduction reaction.
