Abstract

Experimentally, decomposition of NO on the alkalized Pd/Al₂O₃ catalyst is remarkably enhanced at 825-1000 K. The enhancement in N₂ yield may be due to the additional basic sites on the alkalized catalyst that can trap NO molecules. However, at T > 1000 K, due to the fact that the absorbed oxygen in subsurface or bulk of Pd was involved in the formation and desorption of oxygen molecules, yield of oxygen was enhanced.
