Ruthenium Oxide Anode Coatings

SHARE THIS PAGE:

Coatings containing platinum metals oxides have replaced many of the anode materials previously used by the electrochemical industry. The addition of various non-noble metal oxides to ruthenium oxide coatings is known to improve their selectivity and stability, and hence their performance. Now researchers at the Central Electrochemical Research Institute Karaikudi, India, have reported the effects of gradually replacing the titanium oxide in ruthenium-titanium oxide coatings with tin oxide (S. Pushpavanam and K. C. Narasimham, J. Mater. Sci.,1994, 29, (4), 939–942). With constant ruthenium content, the morphology and porosity are determined largely by the ratio of titanium oxide to tin oxide.
