“…a–c. Consistent with other research , with the increase of catalytic temperature, the signal:noise ratio (SNR) showed an obvious maximum, whereas CTL intensity rose gradually. The SNR values attained maxima at voltages around 14 V, with a very slight increase at a higher temperature from CaCO 3 to BaCO 3 .…”

Detection of hydrogen sulphide (H(2)S) was conducted based on cataluminescence (CTL) sensors, using alkaline-earth metal carbonates as catalysts. Optimal working conditions, analytical characteristics and the response properties of the sensor were investigated. CTL intensity examination showed that sensors fabricated with CaCO(3), SrCO(3) or BaCO(3) could be used to detect H(2)S gas sensitively. The optimal sensing temperature was about 320 °C. Under the sensing conditions with temperature at ca. 320 °C and gas flow rate in the range 180-200 mL/min, the linear range of CTL intensity vs H(2)S concentration was 25-500 ppm, with a detection limit of 2 ppm. The response and recovery times of the sensor were within 5 and 25 min, respectively. Also, the sensor had the property of high selectivity to H(2)S with very weak or no obvious response to 14 other gases, such as NO(2), NH(3), hydrocarbons and alcohol.

“…The miniaturized sensing unit using heating filament has low incandescent radiation so as to provide a high signal-to-noise ratio. Under optimized conditions, the linear range for the determination of ethanol vapor was 1.0×10 −3 -1.0 mg·L −1 with an LOD (S/N = 3) of 2.0×10 −4 mg·L −1 (0.1 ppm), which significantly improved the sensitivity by ~3000-fold for ethanol compared with previous CTL sensors with a bulky ceramic substrate as heater [109].…”

The cataluminescence (CTL)-based sensor is a new promising type of chemical transducer, and has attracted much attention of researchers for its potential versatile applications in public safety, emission control and environmental protection. In this review, we briefly introduce the development history of CTL-based sensors and summarize existing explanations of the CTL reaction mechanism as well as three research strategies for mechanism the CTL mechanism. In the following, all the function units of a typical CTL-based sensor system are described and the investigation of the sensor materials. CTL-based sensor arrays, are discussed in detail. We classify the recent novel hyphenated techniques based on CTL coupled to other analysis techniques into the preconcentration-CTL hyphenated technique, nebulization-CTL hyphenated technique, plasma-assisted CTL technique and tandem CTL technique according to the type of analysis combined with CTL and provide a detailed account of novel hyphenated techniques. Owing to the appearance of these novel techniques, the application range of CTL has been expanded as well as the sensitivity and selectivity of CTL system has been greatly improved. Finally, the applications of CTL-based sensor and sensor arrays in the last several years are classified and summarized.
