Spinel metal oxides have the general formula AB2O4 (A, B = Co, Cu, Mn, Ni, etc.) and exhibit high thermal and chemical stability compared to single metal oxides. Therefore, spinel metal oxide structures have attracted greater attention than single-metal oxides in recent years. Traditional noble metal materials have strong catalytic properties and are used in a wide range of applications. In this study, the one-pot electrochemical synthesis of cobalt bismuthate (CoBi2O4) nanostructures, Co(NO3)2.6H2O and Bi(NO3)3 solutions were mixed at a 1:2 ratio. O2 gas was passed through the solution at a constant flow rate. A cyclic voltammogram (CV) was recorded with the cleaned pencil graphite electrode (PGE). This determined the deposition potential at which CoBi2O4 nanostructures could be deposited. The produced CoBi2O4 nanostructures were characterized using various techniques, including XRD, XPS, Raman, and SEM.
