Used as a catalyst in industrial processes, particularly in the treatment of nitrogen oxides in automotive exhaust systems. It helps convert harmful pollutants like NO and NO₂ into nitrogen and oxygen, reducing emissions. Also employed in electrochemical applications, such as in the production of dimensionally stable anodes for chlor-alkali processes. Shows activity in oxidation reactions, making it useful in chemical synthesis and sensor technologies. Its stability at high temperatures allows use in specialized coatings and electronic components.
