“…After the resistance of the PbS sensor is stable, the calculated amount of tested solution is manually injected into the test chamber by a microsyringe, and then, the tested solution is evaporated by a quick evaporator and mixed with air immediately by two installed fans, which constitutes the measurement atmosphere. Afterwards, the test chamber is opened and the PbS sensor begins to recover in air 26,27 . The sensor sensitivity is defined as follows,…”

Star-shaped PbS nanomaterials are synthesized by a hydrothermal method. Morphology and structure of the PbS nanomaterials are analyzed by SEM, HRTEM and XRD. Gas-sensing properties of the as-prepared PbS sensor are also systematically investigated. The results show star-shaped PbS nanostructure consists of four symmetric arms in the same plane and demonstrate good crystallinity. With the increase of ethanol concentration, the sensitivity of the PbS sensor significantly increases and demonstrates an almost linear relationship at the optimal operating temperature of 400 o C. Moreover, the fast response-recovery towards ethanol is also observed, which indicates its great potential on ethanol detection.

“…The test gas with a calculated volume was introduced into the test chamber by a microsyringe. 22 The sensor sensitivity is defined as follows, 23 The sharp and strong intensity of XRD peaks at the two reaction temperatures suggest that the samples have better crystallinity. As reaction temperature is increased to 200 o C, many extra peaks arising from other phases are detected, indicating impurity phase is introduced in the Bi 2 MoO 6 nanomaterials.…”

Bi 2 MoO 6 nanosheets were synthesized by a hydrothermal method. Morphology and structure of the Bi 2 MoO 6 nanosheets were analyzed by SEM, XRD, N 2 adsorption techniques and XPS. Gassensing properties of the as-prepared Bi 2 MoO 6 sensors were also systematically investigated. The results showed the reaction temperature greatly affected the morphology and structure of as-prepared Bi 2 MoO 6 nanosheets. When the reaction temperature reached 170 ºC, the morphology of the Bi 2 MoO 6 nanosheets tended to regular, and pure Bi 2 MoO 6 nanosheets were obtained. The operating temperature determined the gas-sensing properties of the Bi 2 MoO 6 sensor. At this optimal operating temperature of 300 ºC, the sensitivity of the Bi 2 MoO 6 sensor towards 20 ppm nitrogen oxide (NO) reached a maximum of 3.13. With the increase of the nitrogen oxide (NO) concentration, the sensitivity of the Bi 2 MoO 6 sensor also rapidly increased, and displayed an almost linear relationship between them. Additionally, the Bi 2 MoO 6 sensor demonstrated excellent selectivity with respect to several typical interfering gases.
