“…In addition, the selective detection of some analytes has also functioned to promote medical research and clinical diagnosis. [79,80] For example, Yang and colleagues in Lu's group [15] proposed HS-SPME-CTL to determinate acetone associated with diabetes. Real samples of human plasma from people with diabetics were successfully analyzed using this strategy, which opened up clinical applications for CTL sensors.…”

Cataluminescence (CTL), a kind of chemiluminescence emitted at the gas–solid interface during catalytic oxidation reactions, has been developed for many decades as a novel and promising gas sensing technique. In this review, we introduce the origin, basic principles, and mechanisms of CTL sensing systems and summarize the recent advances in CTL sensing, focusing on methodologies and extended applications such as in gas selective monitoring, recognition of complex mixture, evaluation for catalytic property and use in high‐performance liquid chromatography, capillary electrophoresis and gas chromatography detectors. In addition, development prospects and some challenges facing CTL‐based sensing are also discussed.

“…Cataluminescence (CTL) a kind of in situ chemiluminescence, which occurs through catalytic oxidation reactions at gas-solid interfaces [7,8]. On account of its numerous advantages, such as a rapid response, extraordinary sensitivity, high selectivity, good repeatability, and convenience, CTL-based sensors show promising application in environmental monitoring [9,10], material characterization [11,12], food analysis [13,14], catalyst evaluation [15,16], and clinical diagnosis [17][18][19]. CTL-based sensors are considered one of the most attractive and effective tools for gas sensing.…”

In the present work, three kinds of nanosized SnO2 samples were successfully synthesized via a hydrothermal method with subsequent calcination at temperatures of 500 °C, 600 °C, and 700 °C. The morphology and structure of the as-prepared samples were characterized using X-ray diffraction, transmission electron microscopy, selected area electron diffraction, Brunauer–Emmett–Teller analysis, and X-ray photoelectron spectroscopy. The results clearly indicated that the SnO2 sample calcined at 600 °C had a higher amount of chemisorbed oxygen than the SnO2 samples calcined at 500 °C and 700 °C. Gas sensing investigations revealed that the cataluminescence (CTL) sensors based on the three SnO2 samples all exhibited high selectivity toward H2S, but the sensor based on SnO2−600 °C exhibited the highest response under the same conditions. At an operating temperature of 210 °C, the SnO2−600 °C sensor showed a good linear response to H2S in the concentration range of 20–420 ppm, with a detection limit of 8 ppm. The response and recovery times were 3.5 s/1.5 s for H2S gas within the linear range. The study on the sensing mechanism indicated that H2S was oxidized into excited states of SO2 by chemisorbed oxygen on the SnO2 surface, which was mainly responsible for CTL emission. The chemisorbed oxygen played an important role in the oxidation of H2S, and, as such, the reason for the SnO2−600 °C sensor showing the highest response could be ascribed to the highest amount of chemisorbed oxygen on its surface. The proposed SnO2-based gas sensor has great potential for the rapid monitoring of H2S.

“…To date, many different materials have been used to developed CTL-based sensors. Examples include a sensor for detecting formaldehyde and carbon monoxide based on Ptactivated Ce 4 La 6 O 17 nanocomposites [10], an acetaldehyde gas sensor based on PdO-ZnO p-n heterojunction nanostructures [11], an acetone gas sensor based on mesoporous Mg-doped SnO 2 structures [12], a diethyl ether sensor based on nanoparticles of TiO 2 [13], an n-propanol gas sensor based on a composite of SrCO 3 /graphene [14], an H 2 S gas sensor based on enclosed hollow tubular ZnO [15], an acetophenone gas sensor based on nano-Pr 6 O 11 [16], a benzene and toluene sensor based on TiO 2 /SnO 2 [17], and a formaldehyde and ammonia gas sensor based on nano-Ti 3 SnLa 2 O 11 [18]. e sensing material clearly plays a key role in a sensor system, as it directly affects the sensitivity, selectivity, and stability of the sensor.…”

A highly sensitive and selective sensor for isobutyraldehyde (IBD) is demonstrated based on intensive cataluminescence (CTL) emission from the surface of nanosized Sm2O3 particles. The characteristics and optimum conditions for the CTL sensor, including the working temperature, wavelength, and flow rate, were investigated in detail. Under the optimized experimental conditions, the CTL intensity varied linearly with the concentration of IBD, in the two-order-of-magnitude range of 0.015–3.9 μg/mL, with a correlation coefficient (r) of 0.99991 and a limit of detection (LOD), at a signal-to-noise ratio (S/N = 3) of 4.6 ng/mL. The sensor was quite specific: butyraldehyde, methanol, ethanol, acetone, formaldehyde, acetaldehyde, benzene, ethylbenzene, and cumene could not produce significant CTL intensities; specifically, butyraldehyde, ethanol, acetone, and acetaldehyde produced low CTL intensities, with values that were 3.8%, 2.8%, 0.60%, and 0.57% that of IBD. As a test of sensor stability, we found that the relative standard deviation (RSD) of 30 measurements of the CTL at an IBD concentration of 1.6 μg/mL within a period of 72 h was 2.2%, indicating good stability and long service life of the sensor. The sensor was tested against spiked samples containing IBD, and recoveries between 89.7% and 97.4% were obtained with an RSD of 6.1%–8.6%. The performance of the sensor indicated its utility for practical sample analysis.
