Abstract

  The thickness of the nanocomposite films used is 22 and their area is 50 micrometers. The concentration of CO gas used is 20 ppm, proportional to the weight of the nanosensor (0.02%). The plasma technique was used to prepare the (CdNPs) and (CuNPs) nano-metals. The response time for CdNPs was 13.5s at 25°C, 22.5s at 100°C, and 19.8s at 200°C. For CuNPs, the response time was 24.7s at 25°C, 24.7s at 100°C, and 23.4s at 200°C. The FAAS method was used to identify these nanometals and determine their concentrations. Additionally, FTIR, UV-Vs, FESEM, EDX, and XRD methods were used to diagnose it. Additionally, a nanocomposite of oxide and nanometals with a mixing ratio of 10:1:1 is created by preparing graphene oxide using the Hummer process. The (GO/CdNPs) nanocomposite was tested for gaseous sensitivity to CO gas in comparison to the (GO/CuNPs) nanocomposite, and the results showed good sensitivity to the gas.
