“…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.

“…Moreover, the fast response and recovery times of the sensor to n-butanol are found to be 4 s and 10 s (Figure 7d). On top of this, an excellent reversible response-recovery switch can be seen from the five reversible cycles of the sensor, based on CdIn 2 O 4 spheres of up to 300 ppm n-butanol Nanomaterials 2019, 9,1714 7 of 12 at 280 • C (Figure 7e). Taking the n-butanol concentrations of 100 ppm and 300 ppm as examples, long-term stability has been investigated.…”

“…Moreover, explosion or fire may occur if 1.45-11.25% n-butanol is mixed in air when the temperature is higher than its flash point of 35 • C. Consequently, it is highly necessary to effectively detect n-butanol in laboratory and factory settings with fast speed and excellent selectivity. For now, several monitoring methods have been reported for n-butanol detection, in which metal oxide semiconductors such as SnO 2 [8], ZnO [9], WO 3 [10], Fe 2 O 3 [6], and their hybrid-based gas sensors [11][12][13] have drawn considerable attention because of their advantages of sensing properties and low cost. Yet, it is still necessary to develop an n-butanol gas sensor based on novel sensing materials.…”

Cd/In-glycerate spheres are synthesized through a simple solvothermal method. After thermal treatment, these Cd/In-glycerates can be converted into CdIn 2 O 4 spheres. Many characterization methods were performed to reveal the microstructure and morphology of the CdIn 2 O 4 . It was found that pure CdIn 2 O 4 phase was obtained for the Cd/In starting materials at ratios of 1:1.6. The CdIn 2 O 4 spheres are composed by a large number of nanoparticles subunits. The CdIn 2 O 4 sphere-based sensor exhibited a low detection limit (1 ppm), high response (81.20 to 500 ppm n-butanol), fast response (4 s) and recovery (10 s) time, good selectivity, excellent repeatability, and stability at 280 • C. Our findings highlight the possibility to develop a novel gas sensor based on CdIn 2 O 4 for application in n-butanol detection with high performance.
