Embodiment 1
[0021] First configure 0.1M KMnO 4 Solution, bend the cleaned Pt electrode sheet into a cylindrical structure with a diameter of 120mm, connect it to the negative electrode of the power supply through a wire, wrap the top of the carbon fiber cloth tightly on the copper wire, and then connect the copper wire to the positive electrode of the power supply through the wire. Finally, the carbon fiber cloth wrapped with copper wire is bent into a cylinder with a diameter of 30 mm, so that the Pt electrode cylinder and the carbon fiber cylinder or cylinder are coaxially nested (such as Figure 4 shown), the carbon fiber is located inside the center; after completing the above operations, the two are fixed in the KMnO 4 In the reaction bottle of the solution, the copper wire does not touch the KMnO 4 Solution, sealed, connected to an adjustable DC power supply with a voltage of 5V, then placed the entire device in an oil bath at 60°C for 80 minutes, and finally cleaned the removed car...
