Chemical warfare agents (CWAs) are known as poor man’s bombs because of their small lethal dose, cheapness, and ease production. Therefore, the highly sensitive rapid detection CWAs at room temperature (RT = 25 °C) is essential. In this paper, we have developed a resistive semiconductor sensor for RT.

In this study, using graphene oxide (GO), glutamine (G), and Cu(II) nanoparticles, a nanocomposite was prepared. Then, the prepared checked out by various techniques such as X-ray diffraction, Fourier transform infrared, Raman spectrum, scanning electron microscopy, energy-dispersive X-ray, results showed that desired structure successfully Also, three-electrode system utilized to measure electrochemical properties. The specific capacitance of Cu-doped oxide-glutamine (Cu/G-GO) 1838 F g–1 obtained in 1 M H2SO4 aqueous electrolyte under current density 3 A g–1. Moreover, 85.43% initial electrode preserved after 5000 cycles at 20 (10,000 cycles, 73.12%). quantum layer distance GO G-GO functional theory were calculated.
