CeO2 Enhanced Ethanol Sensing Performance in a CdS Gas Sensor

CdS nanowires (NWs) were fabricated through a facile low-temperature solvothermal method, following which CeO₂ nanoparticles were modified on the NWs. The ethanol sensing characteristics of pure CdS and decorated ones with different CeO₂ content were studied. It was found that the sensing performance of CdS was significantly improved after CeO₂ decoration. In particular, the 5 at% CeO₂/CdS comp...

TiO2 based surface acoustic wave gas sensor with modified electrode dimensions for enhanced H2 sensing application

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...

Fluctuation Enhanced Gas Sensing at Modulated Temperature of Gas Sensor

Taguchi gas sensors are commonly used sensors to measure gas concentration. The detection method utilizes only sensor DC resistance changes for determination of various gases concentration. Unfortunately, such technique leads to false results due to cross-sensitivity of gas sensors at presence of other gases. Such adverse effects can be reduced by applying fluctuation enhanced sensing and tempe...

Simple Route to Obtain Nanostructured CeO2 Microspheres and CO Gas Sensing Performance

In this work, nanostructured CeO2 microspheres with high surface area and mesoporosity were prepared by the coprecipitation method, in absence of a template. The reaction between cerium nitrate and concentrated formic acid produced cerium formate, at room temperature. Further, calcination at 300 °C yielded single-phase CeO2 microspheres, with a diameter in the range 0.5-2.6 μm, the surface of t...
