Abstract: | The wheat-leaf Co3O4/CeO2 composite electrode material has been synthesized through a hydrothermal method using cerium nitrate hexahydrate, cobalt nitrate hexahydrate and urea. And its electrochemical performance were analyzed. The experimental results showed that the Co3O4/CeO2 composite electrode material has good electrochemical reversibility and power characteristics, and its capacitive characteristics and high-current discharge characteristics are also superior, making it an ideal supercapacitor material. |
