PROPANOL DETECTION DEVICE FOR THE PURPOSE OF MONITORING THE QUALITY OF THE ENVIRONMENT

Abstract

The aim of this study was to develop and characterize CuO/Cu2O functionalized with AgPt nanostructures for gas sensing applications. Environmental pollution remains a pressing global concern, requiring effective detection methods. Metal oxide nanostructures, such as those based on copper oxides, offer promising solutions due to their sensitivity and selectivity for various gases. The research investigated the morphology and structure of the nanostructures using techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), and Raman spectroscopy. In addition, the nanostructures were functionalized with noble metals such as silver and platinum to enhance their sensory properties. The deposition of polymer layers has been investigated as a method to improve sensor selectivity. The gas sensing properties of the CuO/Cu2O/AgPt nanostructures were evaluated using the Keithley 2400 source meter and showed high sensitivity to gases such as propanol, acetone, hydrogen, and ammonia at elevated temperatures. The results showed that higher operating temperatures result in faster response and recovery times. In addition, the nanostructures exhibited saturation in response at higher concentrations of certain gases. These results highlighted the potential of CuO/Cu2O/AgPt nanostructures in environmental monitoring applications, particularly in industries prone to gas emissions. Overall, this research contributes to the advancement of gas sensing technology for pollution prevention and control efforts.
