| titleOfInvention | Oxygen-doped porous carbon electrode material with high pseudocapacitive activity and preparation method thereof |
| abstract | The invention discloses an oxygen-doped porous carbon electrode material with high pseudocapacitive activity and a preparation method thereof, belonging to the technical field of electrochemical supercapacitors. The resorcinol-formaldehyde resin is obtained by polymerization, washed alternately with water/ethanol, dried, carbonized at low temperature, and activated by low temperature caustic alkali. In the present invention, in the process of caustic alkali activation, the conversion of sp 3 C to sp 2 C structure occurs, and the electrical conductivity of the material is improved; at the same time, the etching and activation of caustic alkali transform the carbon microspheres into porous sheet-like carbon materials , increases the specific surface area, and achieves a balance between good conductivity, porosity, and high oxygen doping content, which facilitates electron transfer and ion transport. When used in the testing of supercapacitor electrode materials, oxygen-doped porous carbon The material exhibits high pseudocapacitive performance. |
