The catalytic activity of a copper(II) salt of polymolybdophosphoric acid (Cu<SUB>1.1</SUB>H<SUB>0.8</SUB>PA) for the reduction of NO with the supporting active carbon into N<SUB>2</SUB> and N<SUB>2</SUB>O was studied at 400 °C using a fixed bed flow reactor. A considerable activity was observable at a stationary state where the spill-over of oxygen left on the active site of the acid to the carbon surface appeared to be rate-determining. The activity of the salt was much higher than for component oxides produced through its decomposition at higher temperatures. This suggested that the active site was characteristic to the salt (very probably the reduced site in the salt). The reaction mechanism in terms of the reaction paths, the N<SUB>2</SUB>O/N<SUB>2</SUB> selectivity, and the roles of the supporting active carbon are discussed based on kinetic investigations.
