Abstract

In this paper, micro gas sensor was fabricated using indium oxide nanowire for effective gas detection and monitoring system. Indium oxide nanowire was grown using thermal CVD, and their structural properties were examined by the SEM, XRD and TEM. The electric properties for microdropped indium oxide nanowire device were measured, and gas response characteristics were examined for CO gas. Sensors showed high sensitivity and stability for CO gas. And with below 20 mw power consumption, 5 ppm CO could be detected.

Facile fabrication of NiO foam@Sn-doped In2O3 nanowire heterosturctures for highly sensitive ethylene glycol gas sensors at low temperatures

Xukun Wang, Wenjian Zhang, Xijuan Li, Xinyi Sui, Guo Liu, Bingsheng Li, Jinyuan Zhou, Erqing Xie, Zhenxing Zhang

Summary: In this study, a p-type nickel oxide foam/n-type tin-doped indium oxide nanowires composite was fabricated for ethylene glycol gas sensing, which showed a unique response to 100 ppm ethylene glycol at a low temperature of 125 degrees C, along with fast response/recovery time. The excellent gas-sensitive performance of the composite can be attributed to the formation of p/n heterojunctions and the In and Sn doping of NiO during ITO growth. This fabrication method provides an effective strategy for building NiO-based heterostructures for high-performance gas sensors.

Highly sensitive SnO2 nanowire network gas sensors

Guillem Domenech-Gil, Jordi Sama, Cristian Fabrega, Isabel Gracia, Carles Cane, Sven Barth, Albert Romano-Rodriguez

Summary: We present a methodology for localized growth of nanowires on micro-hotplates that allows independent adjustment of the device's resistance and gas response. Fabrication of nanowire-containing stripes with or without gaps enables nanowires to bridge current, and we demonstrate this approach with SnO2 nanowire-based chemoresistors. The results show the capability of tailoring nanowire stripe sizes and empty areas along the sensing material, resulting in up to 500 times response increase. The absence of nucleation seeds in the gap areas restricts current flow along the nanowire bridges, enhancing surface conduction controlled by nanowire-gas interaction.

Evaluation of Indium Tin Oxide for Gas Sensing Applications: Adsorption/Desorption and Electrical Conductivity Studies on Powders and Thick Films

Stefan Dietrich, Mihails Kusnezoff, Uwe Petasch, Alexander Michaelis

Summary: The study found that indium tin oxide surfaces are covered with water-related and carbonaceous adsorbates, with carbon monoxide exacerbating this situation. Therefore, when using indium tin oxide for gas sensing applications, the operating temperature should be carefully selected to ensure sensitivity to target gases.

Min Liu, Peng Song, Zhongxi Yang, Qi Wang

Summary: In this study, MXene/In2O3 nanocomposites were prepared by hydrothermal method and their gas-sensing performance was tested. The results showed that the composite had higher response to formaldehyde compared to pure In2O3 samples, with lower optimal working temperature and faster response speed. Therefore, the method of combining MXene with metal oxide semiconductors has great potential in low-temperature gas detection.

Core-double shell ZnO@In2O3@ZnO hollow microspheres for superior ethanol gas sensing

Shichao Wang, Xiaohu Wang, Gaoqun Qiao, Xiaoyan Chen, Xinzhen Wang, Hongzhi Cui

Summary: Core-double shell-structured ZnO@In2O3@ZnO microspheres were successfully synthesized by decorating In2O3 and ZnO on the surface of ZnO hollow microspheres, exhibiting excellent gas sensing properties with high response to gases like ethanol, especially at low concentrations. This superior gas sensing performance was attributed to its high specific surface area, abundant surface defects, and radial electronic modulation mechanism.
