Direct synthesis of CeO2 nanospindles on gold electrode by electrochemical method

In the present study, we reported direct synthesis of CeO2 nanospindle on gold electrode by using cyclic voltammetry (C‐V) method. The method advantages are simple, low cost, room temperature, without using any templates. The synthesized nanospindles were characterized by Field Emission Scanning Electron Microscopy (FE– SEM), Energy Dispersive X‐ray Spectroscopy (EDS) and X‐ray diffraction (XRD). The propery characterization of the samples was studied by electrochemical impedance spectroscopy (EIS) and Photoluminescence spectroscopy (PL). It was found that these nanospindles are approximately 700 nm and diameter of about 100‐200 nm. Optimal parameters such as scan rate, scan cycle, and Ce3+ concentration were also investigated.
