Abstract :
CuAl2O4/CuO nanocomposite were synthesized through the simple and fast
procedure (sol-gel method) in the presence of sodium tetraphenylborate NaB(C6H5)4 as the
novel capping agent. The analysis of CuAl2O4/CuO nanocomposite was performed through
some techniques including, Scanning electron microscopy (SEM), Fourier transform infrared
(FT-IR) spectroscopy, X-ray diffraction (XRD), Energy dispersive X-ray microanalysis
(EDX), and Transmission electron microscopy (TEM). Synthesis of nanocomposite used for
sensitive electrochemical detection of dopamine (DA). The linear range of 0.5-1 μM and 1-20
μM with the detection limit of 0.08 μM for DA, was obtained using differential pulse
voltammetry (DPV) (pH=7.0).
