Preparation and characterization of Ti/Diamond electrodes

Boron doped diamond films were deposited on Ti substrates by CVD. Raman spectroscopy reveals small amts. of nondiamond carbon. According to SEM and XRD, the diamond films are polycryst. with preferential {112} crystallite orientation. Electrochem. measurements show that the Fe(CN)63-/4- couple behaves in a quasi-reversible manner at the Ti/diamond electrode. The main reason of the successful prepn. of the Ti/diamond electrode is the formation of an conductive TiC interlayer between the Ti substrate and the diamond coating. [on SciFinder (R)]
