abstract:
A study over Sb-promoted tin oxide nanopowders for sensing applications is reported. SnO2 nanopowders pure and promoted
with 5wt% of antimony were prepared by wet chemical methods and widely characterized by TEM, XRD, and XPS techniques.
Thick film resistive sensors were fabricated by depositing the synthesized nanopowders by drop-coating on interdigited alumina
substrates. The sensing characteristics of the pure SnO2 and Sb-promoted sensors for the monitoring of trace level of NO2
were studied. The response of the sensors to water vapor was also investigated, revealing that Sb acts favorably eliminating the
interference of humidity.
