Summary: In this study, zinc-doped indium oxide nanowires with high crystallinity and appropriate morphologies were synthesized and their gas sensing properties were investigated. The electrical resistivity of the nanowires increased after doping with zinc, leading to improved gas sensing performance. X-ray photoelectron spectroscopy analysis confirmed the increased oxygen vacancies due to zinc doping, which enhanced gas molecule adsorption. The doped nanowires exhibited higher response to reducing gases compared to undoped nanowires at low concentrations and temperatures.

Summary: The sensing response of metal oxides activated with noble metal nanoparticles is affected by changes in the chemical state of the elements. In this study, a PdO/rh-In2O3 gas sensor was investigated for H2 gas detection. The composition and chemical state of elements were examined during operation. It was found that the sensor showed a series of structural and chemical transformations, leading to a decrease in sensing response.

Summary: This study successfully synthesized cubic nanocubes of pure and In-doped WO3 materials using a one-pot hydrothermal method, and evaluated their morphological and microstructural features using various techniques. Gas sensing tests were performed at room temperature using triethylamine (TEA) as the test gas, and the 5% In-WO3 sensor showed the best response. The results suggest that In-doping can enhance the gas sensing performance, possibly due to the increase in oxygen vacancies and surface adsorbed oxygen, as well as the large specific surface area.

Summary: A sandwich-structured hollow nanofiber material, In2S3/In2O3/In2S3 (ISOS HNF), was designed using electrospinning and postvulcanization treatments. The ISOS HNF material effectively overcomes the blocking effect in core-shell heterojunction sensors, and shows improved gas response due to the double In2S3/In2O3 heterointerfaces and the porous In2S3 coatings that enhance gas diffusion.

Summary: A new plasma-enhanced ALD process for molybdenum oxide thin films was developed using a specific molybdenum precursor and oxygen plasma. The films showed typical ALD characteristics and could achieve different crystalline structures and compositions by adjusting the process parameters. The sensitivity to hydrogen gas was demonstrated, and a correlation between crystallinity, oxygen vacancies, and gas sensitivity was observed.

Summary: Indium oxide hollow cubes were synthesized using a simple hydrothermal technique and calcination process. The resulting crystalline form was cubic bixbyite-type with high purity. Urea was used as an alkaline source to create indium-urea complexes and control the shape of the product. Among the different In2O3 samples prepared with varying amounts of urea, In2O3-5 showed the best performance, with a hollow cubic structure, large specific surface area, and small grain size. The In2O3-5 sensor exhibited high sensitivity and selectivity for C3H8 at its ideal operating temperature.

Summary: In this study, three types of In2O3 nanoparticles decorated with Au, Pd, and Pt nanoparticles were synthesized by thermal decomposition method, and their effects on sensitivity to CO gas were investigated. Au-decorated In2O3 nanoparticles exhibited the highest sensitivity, which can be attributed to the high oxygen vacancies on the In2O3 surface due to Au nanoparticles, leading to an increase in resistance.

Summary: In this study, In2O3/PANI composites were synthesized using the hydrothermal technique to explore their sensing capabilities for NO2 gas. The gas sensing properties, such as response/recovery time, optimal temperature, and recyclability, were investigated by analyzing the morphology, purity, and crystal structures of the samples. The In2O3/PANI-1 sensors exhibited high responses, quick response and recovery times, and a low detection limit to NO2 gas at a working temperature of 250 degrees C. The fundamental detecting mechanism for NO2 gas and the electrical characteristics of the In2O3/PANI composites were also discussed.
