Abstract
A sensor sensitive to hydrogen peroxide vapor based on Fe2O3:ZnO (80 : 20 wt %) nanostructured film was studied. Investigation of the Fe2O3:ZnO sensor has been carried out by impedance spectroscopy. Based on the analysis of the frequency dependences of the real and imaginary parts of the complex impedance, the equivalent electrical circuit for the studied sensor structure was proposed, the parameters of its constituent elements were estimated, and approximating curves were computed. Scanning electron microscopy (SEM) images of the Fe2O3:ZnO film showed a nanoparticle structure. This type of sensor can be used in alternating signal-based detectors for sensing the hydrogen peroxide vapors, at the same time the sensor must be tuned to achieve maximum sensitivity by selecting an appropriate operating frequency range.
