“…The phenomenon was observed during the catalytic oxidation of carbon monoxide on a thoria surface by Breysse et al and was defined as cataluminescence (CTL) [21]. Applications of the luminescence have been developed as a means of revealing intermediate stages in adsorption and catalysis [22]. The nanosized material-based sensing mode utilizing the phenomenon of CTL shows a high sensitivity and wide linear response for the determination of volatile organic vapors (VOCs) and gas samples.…”

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.

“…Cataluminescence (CTL) is a kind of chemiluminescence (CL) produced on the surface of solid material during the catalytic oxidation of volatile organic vapors (17–19). CTL on the surface of many nanomaterials has been extensively studied by several groups (17–28). A series of CTL sensors or cross‐reactive sensor arrays as viable tools for gas or VOCs analysis were developed using nanoparticles as sensing materials due to their high selectivity, fast‐response, long lifetime and relatively low cost for instrumentation, as compared with MS‐based methods.…”

We report a simple gaseous sensor for the sensitive detection of trace 2-propanol in exhaled breath using in situ enrichment and cataluminescence detection method on the surface of nanomaterials. The influences of heating voltage and absorption time on the CTL intensity were discussed, respectively. In the selected conditions, the linear range of 2-propanol concentration is 60-600 ppbv and the detection of limit is 11 ppbv. Moreover, the lifetime and selectivity of the sensor were also investigated. It has the potential to diagnostic volatile organic compounds in human breath.
