Fabrication and Characterization of MWCNTs Decorated ZnO Nanograins Based Sensor for Enhanced Performance Toward CO2 Gas

Popis výsledku v původním jazyce

In this study, a zinc oxide sputtering target is synthesized and nanostructured ZnO film is obtained using simple solid-state reaction and RF (radio frequency) magnetron sputtering methods, respectively. The surface of the ZnO film is functionalized by saturating it with MWCNTs (multi-walled carbon nanotubes) using the electron-beam deposition method to produce a high-performance CO2 sensor. The obtained CO2-sensitive material is subjected to multifaceted structural, morphological, crystallographic, and elemental studies using a film thickness measurement profiler as well as scanning electron (SEM), transmission electron (TEM) microscopies, and energy dispersive X-ray (EDX), X-ray photoelectron (XPS), and Fourier transform infrared (FTIR) spectroscopies. The CO2 sensing characteristics of the ZnO/MWCNTs nanostructured resistive sensor designed onto the multi-sensor platform are carefully studied in the temperature range of 25-250 degrees C with and without UV (ultraviolet) irradiation. The temperature of 150 degrees C without UV irradiation is confirmed as the preferable operating point where the response values are swiped from 2.5 to 5.7 corresponding to the CO2 concentration range of 100-5000 ppm, respectively, with the reproducible appearance of the real-time curves. The high performance of the ZnO/MWCNT sensor makes it a likely candidate for successful incorporation into CO2 detectors.
