| Abstract
| - The instability of the commonly adopted support (e.g., Ti, Ti−Pd alloys, Ta) for the preparation andcharacterization of different electrode materials has been overcome by depositing the electrode material ofinterest (RuO2) on conductive, boron-doped diamond (BDD). The present paper reports results on the modelchlorine evolution reaction, investigated at BDD surfaces modified by RuO2 loadings of 1.2 × 1013, 6.0 ×1014, and 2.65 × 1016 molecules cm-2. A radical spillover mechanism is proposed for the reaction occurringat the electrode having the lowest noble-metal oxide loading.
