Summary: In recent years, the two-dimensional layered material MXene has gained significant attention in the field of sensors due to its large specific surface area and rich active sites. By preparing SnO2/MXene composites using multilayer Ti3C2TX and SnO2 microspheres, the gas-sensing properties of pristine SnO2 have been enhanced. The composite was used to fabricate low power consumption resistance-type gas sensors on a microelectromechanical system (MEMS) platform. The results showed that the SnO2/MXene sensor with the best composite ratio greatly improved the gas sensitivity of SnO2 sensor, particularly to ethanol gas. The composite also accelerated the response recovery speed of the sensor.

Summary: In this study, undoped and Pd-doped SnO2 films were fabricated on alumina substrate using screen printing technology. The microstructural properties of the deposited sensing film were characterized using XRD and AFM, showing a decrease in crystallite size, grain size, and roughness parameter with Pd doping. The response of the sensor to ethanol gas was found to be maximum for 1 wt% Pd-doped SnO2, with an observed response/recovery time of approximately 41 s/125 s. The improvement in sensing behavior towards ethanol gas was attributed to the reduction in crystallinity and roughness of the film.

Summary: In this study, a Micro Electro Mechanical Systems (MEMS) sensor was fabricated for testing low concentration gas sensing of sulphur dioxide (SO2). The performance of a single layered tin oxide (SnO2) sensing layer and a double layered heterojunction structure of nickel oxide and tin oxide (NiO/SnO2) were compared, and it was found that the NiO/SnO2 double layered sensor had better sensing characteristics due to the formation of p-n junctions. The maximum sensing response of the NiO/SnO2 sensor was recorded as 20% at 400 ppb SO2 gas concentration, and 30% at 2000 ppb.
