Abstract

In order to research and improve gas sensitive performance of PdO sensitive electrode

La and Mg are employed to dope PdO

it is found by comparing the characterization of pure and doped PdO that doping not only change lattice parameters but also influence the defects. Ni and La-doped PdO sensitive electrode enhance gas sensitivity of sensor to propylene. According to effect of different doping on PdO

discuss influence of defect of oxide on the catalytic activity. The oxygen vacancies in the lattice can effectively increase the catalytic activity of the oxide

thus the sensor based on doped sensitive electrode has higher sensitivity. The selectivity testing on doped-PdO sensitive electrode is carried out on oxygen and various gases

the results indicate the sensor has higher selectivity to propylene.
