A cataluminescence sensor based on α-MoO₃ nanobelts with low working temperature for the detection of diethyl ether

A novel cataluminescence (CTL) sensor was firstly fabricated utilizing α-MoO₃ nanobelts as sensing material, which possesses lower working temperature of 120 °C for detection of diethyl ether gas. Under optimal conditions (200 mL min⁻¹, 120 °C, 440 nm), as-made CTL sensor shows a wider detection range of 9.0–2000 ppm with a lower limit of detection of 7.5 ppm. The respond and recovery time were 16 s and within 2 s, respectively. Meanwhile, as-made CTL sensor exhibits an outstanding selectivity towards other 11 interferences. Besides, the highly stable signals were also obtained with the relative standard deviation of 2.60%. In general, α-MoO₃ nanobelts as a sensing material have the potential application prospect in CTL sensor for detection of diethyl ether.
