Abstract

An electrode for an ozone generator or chlorine generator includes an electrically conductive substrate, a doped-Si layer disposed over the conductive substrate, and a boron-doped diamond (BDD) layer disposed over the doped-silicon layer. The doped-silicon layer defines a discrete architecture that maintains adhesion throughout a high temperature CVD boron-doped diamond process. Another electrode having a PVD nitrogen-doped diamond (ta-C:N) layer disposed over a conductive substrate is also provided.
