Conventional electrochemical sensor electrodes have poor electrical conductivity due to their large surface impedance. Therefore, electrochemical sensing of carbon-coated metal oxide nanoparticles is proposed. Based on the experimental preparation, the preparation of carbon-coated metal oxide nanoparticles Fe304@C and sensors required for the experiment were completed by using chemicals and reaction instruments. The Fe304@C/SPEs studied were tested in a three-level system. Fe304@C/SPEs can effectively reduce the surface impedance of sensor electrodes, promote the movement of electrons, and improve the conductivity of electrochemical sensors.
