Process for preparing an electrode for electrolytic cell having a coating of a single metal spinel, Co{hd 3{b O{HD 4

摘要

Electrodes particularly suitable for use as anodes in electrolytic cells are prepared by coating an electrically-conductive substrate with a thermally-decomposable inorganic cobalt compound and then thermally oxidizing the inorganic cobalt compound under conditions at which the single-metal spinel, Co3O4, is formed.
