General description
Palladium(II) oxide (PdO) is a p-type semiconductor with a band gap of 2.2-2.7 eV. It is widely used as an efficient catalyst for oxidation reactions of hydrocarbons and for fabrication of gas sensors.
Application
Ceria supported Palladium(II) oxide can be used as a catalyst for ozonation of oxalate, to enhance the degradation of recalcitrant organics in polluted water. PdO provides active sites for the decomposition of ozone to surface atomic oxygen. Itcan be used as a cocatalyst for partial oxidation of alcohols on the WO3catalyst.

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
