Background: In this study, Carbon Nanotubes (CNT) were synthesized by the CVD method at 950°C. CNT and metal ZnO nanocomposites synthesized by ball mill procedure were examined. Stability of nanocomposite was attained by cationic Ion Liquid (IL), 1-tetradecyl-3 methylimidazolium chloride, structural morphology material characterized by Fourier Transform Infrared (FTIR) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM), and Ultraviolet- Visible (UV-Vis) spectroscopy. Furthermore, these materials were analyzed by Energy Dispersive X-ray spectroscopy (EDX) to examine the percentage of elemental composition. It was found that Current-Voltage (I-V), characterized by electrical properties, was highly responsive to resistance variation, and easy recoverable high sensitivity was the main feature of the CO2 gas sensing properties.

Objective: This study aimed at combining carbon nanotube and zinc oxide nanoparticles in different ratios and optimizing coating methods used for sensor applications.

Methods: CNT was synthesized by the chemical vapor deposition method, and zinc nanoparticle was developed by the ball mill method. Moreover, spin coating and dip coating methods were optimized on a glass surface.

Results: FTIR spectrum results revealed that the existing hydroxyl group and C group of CNT-ZnO nanoparticles were covered by the surface-active site of ZnO. The size and composition of the CNTZnO were confirmed by FESEM EDAX studies. The absorption and transmittance wavelengths of CNT-ZnO nanoparticles were recorded by UV-Visible spectroscopy. The I-V property showed that the drain current and voltages were varied by gas, implying that materials were suitable for applications.

Conclusion: This module can be used to monitor CO2 gas application instruments with the help of software. In the future, this module and techniques could be used to study stress sensors and piezoelectric applications.

Keywords: Carbon nanotubes, nanoparticle, electrical properties, gas sensors, photodetectors, spectroscopy.
