Abstract:
The present investigation dealt with the fabrication of H2 gas sensor based on Pd doped SnO2. Porous SnO2 nanostructured film were fabricated by spray pyrolysis route using tin chloride pentahydrate (SnCl4.5H2O) solution as starting material, and PdCl2 as a dopant. Resistance measurements at different temperatures and concentration of H2 have been carried out with the samples. Microstructure and palladium dopant have been found to be critical factors determining the gas sensing properties of Pd/SnO2 specimens. The comparative gas sensitivity tests showed the excellent H2 sensing properties of the sensor in air was suggested to arise mainly from the improvement of gas absorption and catalytic effect of nano Pd dopant.
