Synthesis and Characterization of Tin Oxide Nanoparticle for Humidity Sensor Applications

Abstract

Tin oxide nanoparticle was successfully prepared by the chemical digestion method from the starting material as SnCl2. The SnO2 material was characterized by X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM) and Selected Area Electron Diffraction (SAED). The SnO2 was an n-type material preferred to humidity sensing property towards the moisture. The response and recovery time of sensor was calculated as 129sec and 206sec respectively. It has exhibited better efficiency compared with the bulk SnO2 material. Additional Weight loss, EDS, FT-IR and resistivity measurements were also presented.

A review on production, storage of hydrogen and its utilization as an energy resource

“…Most of these hydrogen sensors show reduced sensing property at low temperature and concentration, which is further adversely affected by the presence of moisture [128,129]. In a humid environment, the oxide sensors that also offer excellent sensitivity toward humidity, looses the selectivity for hydrogen [130,131].…”

Thermal degradation mechanisms of epoxy composites filled with tin particles

“…The peak present at 72.458 as shown by square in Fig. 3 could be due to the metastable tetragonal Romarchite structure of SnO [23,24], existing in smaller proportions in the composites. The remaining peak at 73.328 with relatively low intensity, as shown by star in Fig.…”

TiO2/LiCl-Based Nanostructured Thin Film for Humidity Sensor Applications

“…24 It is important to note that the morphology of the sensor material plays a substantial role in the overall sensor performance . 19,20,25 A number of different nanostructures were studied with respect to humidity sensing, 20 such as nanowires, 26,27 nanorods, 19,20,27 nanobelts, 27 and nanotetrapods, 28 together with more usual round shaped nanoparticles 29 and meso-pore materials. 30 However, increasing the functionality of the material by controlling shape and arrangement of nanoparticles usually requires sophisticated and expensive deposition techniques, such as chemical vapor deposition (CVD), physical vapor deposition (PVD), magnetron sputtering, pulsed laser deposition, etc.…”
