A novel gaseous pinacolyl alcohol sensor utilizing cataluminescence on alumina nanowires prepared by supercritical fluid drying

Peony‐like Na 2 Mg(CO 3 ) 2 : a nanomaterial with the characteristic of high sensitivity and rapid response for the detection of alcohols

“…Compared to previous reports [10, 13, 21], the detection temperature of the presented sensor based on Na 2 Mg(CO 3 ) 2 is relatively low, and the gas flow rate is similar or lower.…”

“…The average one‐time response cycle of methanol is 50 s, ethanol is 15 s, n‐propanol is 24 s and n‐butanol is 28 s. The above data may serve as a basis for distinguishing the four alcohols. Besides, the material has the characteristics of rapid response to all four alcohols, and the response time is between 1 and 2 s. Yu et al [10] has established a CTL sensor based on Al 2 O 3 nanowires to detect pinacolyl alcohol. The response time of the sensor is <100 s. Yu et al [13] reported a CTL gas detector for alcohols using zinc oxide‐doped tin dioxide nanowires as the sensing materials with a response time of 7 s. Compared to some CTL sensors for the detection of alcohols, the sensor using Na 2 Mg(CO 3 ) 2 as sensing material has exhibited a potential advantage of rapid detection.…”

“…Tang et al [9] established a CTL‐based sensor for the detection of ethanol based on ZnO nanomaterials, which can achieve a low‐detection limit of 0.7 ppm and sensitive response. Yu et al [10] developed a new method for the detection of gaseous pinacolyl alcohol using the principle of CTL. Therefore, it is feasible to use nanomaterials to detect alcohols [11–14].…”

A novel gaseous dimethylamine sensor utilizing cataluminescence on zirconia nanoparticles

“…In the 1990s, Nakagawa et al developed a sensor using γ-Al 2 O 3 as a sensing material for the determination of trace ethanol and acetone (11)(12)(13)(14). In recent years, CTL gas sensors based on nanomaterials, such as TiO 2 nanoparticles, were used for gas sensing with high sensitivity, selectivity and long lifetime of the gas sensor (15,16 (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34).…”
