· PdO

Palladium oxide (PdO) is a p-type semiconductor compound commonly used in gas sensing applications, catalysis, and thin-film electronic devices. The material is widely employed in palladium-based hydrogen sensors, oxygen sensors, and catalytic converters due to its strong interaction with gases and excellent electrochemical properties. PdO is also investigated for resistive switching memory devices and as a component in advanced functional coatings, where its semiconductor characteristics and chemical reactivity make it particularly valuable in environments requiring selective gas detection or catalytic performance at moderate temperatures.
