The influence of gold nanoparticles on the conductivity response of SnO2-based thin film gas sensors

A Simple Dip-Coating Method of SnO2-NiO Composite Thin Film on a Ceramic Tube Substrate for Methanol Sensing

“…At present, numerous research workers are contributing to research on methanol sensing. G. Korotcenkov et al fabricated Au-modified SnO 2 films through a successive ionic layer deposition method, which exhibits a high response to 50 ppm methanol [17]. A CdS-doped tin oxide thick film made up by Lallan et al [18] employing a screen-printing technology has a 70 response and 100 s recover time to 5000 ppm methanol.…”

Multisensory Gas Chromatography for Field Analysis of Complex Gaseous Mixtures

“…The effect of monometallic nanoparticles was found to have a significant impact on the sensor performance. At the same time, it was shown that different metal doping (Au vs. Pd) might have different effects on conductivity of the main oxide (SnO2) and sensing mechanisms [55,56]. In our work, we developed a novel SnO2 gas sensor based on Au/Pd bimetal nanoparticles by combining the best theories and observations reported by different research groups over the years.…”

Effect of the sheet thickness of hierarchical SnO 2 on the gas sensing performance

“…Several reports concerning the controlling of dimensionality of SnO 2 morphology to enhance its gas-sensing performance can be found in open literature as well [6,39,19,33,40]. However, the fabrication of 3-D hierarchical SnO 2 flower assembled from nanosheets with different thickness has been rarely investigated, in spite of its great potential of resulting in unexpected and unprecedented gas-sensing behaviors.…”

“…Among various metal oxide nanomaterials [1][2][3][4][5][6][7], tin oxide is of great importance owing to its physical properties that are relevant for many emerging applications such as gas sensor [8][9][10][11], photo catalyst [12][13][14][15], supercapacitor [16][17][18][19] and electrode materials [20][21][22].…”
