Abstract :
According to a WHO report, neurological illnesses claim the lives of 6.8 million people each year. Dopamine detection in bio fluids is essential in the medical field for disease diagnosis and early disease detection. BiVO4 and various concentrations of rGO-loaded BiVO4 were created in this study using a hydrothermal technique and a reflux method. BiVO4 and rGO/BiVO4 nanocomposite production is confirmed by the various analyses. Glassy carbon electrode (GCE), BiVO4/GCE, 5rGO/BiVO4/GCE, 15rGO/BiVO4/GCE, and 30rGO/BiVO4/GCE nanocomposite have electrochemical active surface areas of 0.0747, 0.0585, 0.06696, 0.0714, and 0.0774 cm2, respectively. The 30rGO/BiVO4 nanocomposite demonstrated a significant electrocatalytic current for dopamine oxidation. The 30rGO/BiVO4 nanocomposite showed a greater catalytic current in pH 3 phosphate buffer solutions (PBS) compared to pH (4-7) and was selected as the ideal pH.
