Thermodynamic reactions of formation of oxide compounds of platinum, rhodium and palladium were analyzed. It was found that the existence of gaseous platinum oxides in the temperature range 1200-1300°K is unlikely from the point of view of thermodynamics. The most thermodynamically stable under these conditions are the oxides Rh2 O and Rh2 O3 . The existence of palladium (II) oxide in the condensed state is thermodynamically possible only up to a temperature of 1150°K. Proposed ways to further study the reduction of losses in the oxidation of NH3 .
