Sb-SnO2-Nanosized-Based Resistive Sensors forNO2Detection
[摘要] A study over Sb-promoted tin oxide nanopowders for sensing applications is reported.SnO2nanopowders pure and promoted with 5 wt% of antimony were prepared by wet chemical methods and widely characterized byTEM, 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 pureSnO2and Sb-promoted sensors for the monitoring of trace level ofNO2were studied. The response of the sensors to water vapor was also investigated, revealing that Sb acts favorably eliminating the interference of humidity.
