An electrode (22) formed from a layer (24) of tetrahedral carbon doped with nitrogen (taC:N) has both electroanalytical and electrosynthetic applications. The electrode includes a substrate material (26), such as a silicon wafer, for supporting the taC:N layer. The electrode has good durability under a high anodic potential and high selectivity for conversion of chloride ions to chlorine, and for other electron transfer reactions. The electrode is readily formed at ambient temperatures by vacuum deposition of carbon and nitrogen ions on to the substrate. Masking of the substrate during deposition allows the formation of microelectrode arrays.

1. An electrochemical system comprising:an electrode at which an oxidation or reduction reaction takes place including: a substrate, and a layer of a material deposited on the substrate, the layer consisting essentially of carbon and nitrogen, the layer having a nitrogen concentration of at least about 5 atomic %; an electrolyte in contact with the electrode; and a counter electrode.
