Ce-doped LaCoO3 film as a promising gas sensor for ethanol

Multi-walled Carbon Nanotube Film Sensor for Ethanol Gas Detection

A kind of resistance-type multi-wall carbon nanotubes (MWNTs) film sensor was fabricated using layer-by-layer self-assembly, and an astable multivibrator circuit was designed for resistance measurement. The electrical properties of MWNTs film sensor were investigated, and also its ethanol gassensing properties with varying gas concentration are characterized at room temperature. The experiment ...

ZnO:Al Thin Film Gas Sensor for Detection of Ethanol Vapor

The ZnO:Al thin films were prepared by RF magnetron sputtering on Si substrate using Pt as interdigitated electrodes. The structure was characterized by XRD and SEM analyses, and the ethanol vapor gas sensing as well as electrical properties have been investigated and discussed. The gas sensing results show that the sensitivity for detecting 400 ppm ethanol vapor was ~20 at an operating tempera...

NANOSTRUCTURED ZnCo2O4THICK FILM AS AN ETHANOL SENSOR

Semiconductive nanometer-size material ZnCo2O4 was synthesized by a solution combustion reaction of inorganic reagents of Zn(NO3)3. 6H2O, Co(NO3)3.6H2O and glycine as a fuel. The process was a convenient, environment friendly, inexpensive and efficient preparation method for the ZnCo2O4 nanomaterial. The synthesized materials were characterized by TG/DTA, XRD, EDX, SEM, and TEM. Conductance res...

NANOSTRUCTURED Fe2O3 THICK FILM AS AN ETHANOL SENSOR

Thick films of AR Grade nano Fe2O3 material with n-type semiconducting properties were prepared and tested for their gas sensing performances. Thick films of the materials were prepared by screen printing technique. The gas sensing performance was studied using static gas sensing system. The material was tested for various gases such as CO, CO2, NH3, Cl2, H2, LPG, ethanol and H2S. The nano Fe2O...
