US 2014/0151219 A1 · SILVER ELECTRODE COATED WITH CARBON NANOTUBES

Abstract

The silver electrode coated with carbon nanotubes is an indicator electrode for microtitrimetry by differential electrolytic potentiometry. The electrode is made by first positioning at least one silver wire electrode within a reaction zone of a floating catalyst chemical vapor deposition reactor. A ferrocene catalyst is evaporated within the floating catalyst chemical vapor deposition reactor, and an inlet gas is fed therein to carry the evaporated ferrocene catalyst into the reaction zone. The inlet gas includes hydrogen and a carbon source, such as acetylene. The reaction zone is then heated for deposition of carbon onto the at least one silver electrode to form at least one silver electrode coated with carbon nanotubes. The electrode is cooled and then removed from the reactor.
