Summary: In this study, BaSnO3 nanoparticles were obtained using a novel sol-gel process, and their gas sensing behavior was compared with conventionally hydrothermally prepared BaSnO3. It was found that the sol-gel obtained BaSnO3 showed increased sensitivity and selectivity to H2S, and the addition of La3+ further improved its sensing behavior. The surface chemistry played a crucial role in determining the gas sensing properties.

Summary: This study fabricated high-performance SnO2 thin-film transistors (TFTs) at temperatures below 300 degrees C using the combustion-assisted sol-gel method. The results showed that the combustion-assisted solution process significantly increased the field-effect mobility of SnO2 TFTs compared to the conventional solution process, potentially enabling low-cost solution-processed electronics.

Summary: The study investigated the influence of nanosized gold state on the adsorption-sensitive properties of tin dioxide under CO, CH4, and C2H5OH vapor detection. It was found that adding gold colloidal particles with sizes ranging from 1.9-3.5 nm can enhance sensor response, with different sensitivities observed for different gases in SnO2-Au composite materials.

Summary: The SnO2-CuO composite nanoparticles fabricated as an ethanol gas sensor exhibit excellent sensitivity and selectivity to ethanol, with short response recovery time and good linear relationship between response value and ethanol concentration, mainly due to the special heterostructure and synergistic effect between tin oxide and copper oxide.

Summary: Multiferroic BiFeO3 particles with size of about 50 nm and good crystallinity were prepared via a simple sol-gel method and annealing. The VOCs sensing properties of BiFeO3 sensor were tested under both traditional thermal excitation and synergetic thermal-magnetic excitation, and the results showed improved performance under the latter condition. The effect of magnetic field on the sensor can be attributed to decreased defects on domain walls, excitation of gas molecules, and activation of surface-absorbed oxygen species.

Summary: Pd-modified Sb-doped SnO2 nanomaterials were prepared using a hydrothermal reaction and reduction method. The samples exhibited uniform doping of Sb within the SnO2 lattice and successful incorporation of Pd on the surface. Compared to pristine SnO2, the material with 3 mol% Sb doping and 7 wt% Pd decoration showed the highest response to hydrogen gas at high temperature, as well as excellent selectivity and cycling stability. The improved sensing performance was attributed to changes in the energy band structure, lattice distortion-induced oxygen vacancies, and strong metal-support interaction between Pd and SnO2.

Summary: Porous nanocomposites using two and three-component systems were created for gas sensors with the sol-gel method. The Langmuir model and the Brunauer-Emmett-Teller theory were used for calculations to understand the physical-chemical processes during gas adsorption. X-ray diffraction, thermogravimetric analysis, and other techniques were used to analyze the interaction between components and determine optimal annealing temperature. Introduction of a semiconductor additive increased the sensitivity of the nanostructured layers to reductional reagent gases.

Summary: Metal oxide n-type SnO2 nanoparticles were synthesized via sol-gel method and p-type reduced graphene oxide (rGO) were loaded on SnO2 nanoparticles using sonication process. The composition of rGO affected the structure, morphology, composition, optical and electrical characteristics of SnO2/rGO nanocomposite. The formation of SnO2/rGO nanocomposite was confirmed through deviations in XRD, Raman and bandgap, and the electrical conductivity and heterojunction parameters were improved compared to pure SnO2, making it suitable for room temperature gas sensors.

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: Palladium-containing materials based on antimony-doped tin dioxide have been developed for gas-sensitive semiconductor sensors, showing significant response to CO, H-2, and light hydrocarbons. The sensor response value for each gas is highly dependent on the palladium content, with the optimal operating temperature determined by the reactivity of the gases being studied.
