Summary: A novel raisin bread-structured film, fabricated by mixing two different types of oxide hollow spheres, has been developed for the selective and sensitive detection of carcinogenic benzene. The film demonstrated high selectivity to less reactive benzene compared to pure SnO2 or Pd-Co3O4 hollow sphere films. This work provides a simple and rational strategy to achieve gas selectivity to chemically stable benzene and has the potential to advance the development of portable devices for monitoring airborne benzene.

Summary: Designing heterostructure materials at the nanoscale is a well-known method to enhance gas sensing performance. In this study, ZnO/SnO2 heterostructures were grown on alumina substrates using the ultrasonic spray pyrolysis method. The results showed that the sensitivity of the sensor to H2S gas can be altered by changing the zinc chloride content in the precursor, and the heterostructures with a 5:1 ratio of ZnCl2 to SnCl2·2H(2)O exhibited the highest response. The gas sensing mechanism of the ZnO/SnO2 heterostructures was analyzed and attributed to the formation of the heterostructure between ZnO and SnO2.

Summary: This study investigates the sensitivity and selectivity of Zn-substituted SnO2 nanoparticles towards formic acid, demonstrating their potential for ultrasensitive and selective detections of HCOOH in practical applications. The results show that a sensing layer with the optimum Zn content of 0.2 wt% provided a remarkably high response towards 1000 ppm HCOOH, indicating a significant improvement in performance compared to undoped samples. Additionally, good selectivity against various volatile organic compounds was achieved, highlighting the promising applications of the flame-made Zn-substituted SnO2 sensors.

Summary: Porous (pr-)SnO2-based powders were synthesized using ultrasonic spray pyrolysis with home-made polymethylmethacrylate (PMMA) microspheres as templates. The addition of CuxO to the pr-SnO2 powder improved its sensing properties for acetone and toluene. The 0.8 wt% Cu-added pr-SnO2 sensor showed the highest acetone response at 350 degrees C. The addition of CuxO decreased the concentration of carrier electrons and the acetone-oxidation activity, leading to the improvement of the acetone-sensing properties of the pr-SnO2 sensor.

Summary: In this study, SnO2 thin films were deposited through spray pyrolysis and tested for gas sensing at 27℃ (room temperature) towards different gases. The films showed consistently low response of approximately 1 when exposed to various VOCs. Hall measurements were used to determine the type, concentration, and mobility of charge carriers, which were found to hinder its performance at room temperature.

Summary: CuO-based thin films doped with varying Ce concentrations were prepared using chemical spray pyrolysis. The doping of Ce led to modulation of the bandgap and successful substitution of ions in the CuO matrix. The morphology of the films changed with increasing Ce doping. The 4% Ce thin film showed the highest gas sensing capabilities for ethanol and exhibited a chemosorption mechanism.

Summary: Thin film technology offers possibilities and advancements in gas sensor devices. Sb-doped nanometer thin-SnO2 films were developed for CO/NH3 gas detection. The structural, surface, optical, and resistivity properties were investigated as a function of film thickness. ATO thin films showed enhanced response towards CO/NH3 gas detection with better stability and selectivity for CO gas. The results indicate the potential application of nanometer ATO films for enhanced gas detection.
