Abstract
Method of autoclave thermolysis of ammoniac complex compounds of ruthenium was used to obtain metallic electrically conducting ruthenium coatings with a thickness of 1–3 μm on a zirconium dioxide ceramic. Ruthenium in a coating is in the highly dispersed metallic state. A stable operation of Ru/ZrO2/Ru as an electrochemical sensor for nitrogen and carbon oxides in a gas mixture of nitrogen with CO and NO at temperatures above 500°C was demonstrated. The results obtained indicate that the high-priced platinum can be replaced with the less expensive ruthenium in fabrication of electrochemical gas sensors.
