| titleOfInvention | A kind of preparation method and application of nitrogen and phosphorus doped porous hollow carbon nanofibers |
| abstract | The invention relates to the technical field of supercapacitors, and discloses a nitrogen- and phosphorus-doped porous hollow carbon nanofiber, which has a unique hollow and porous structure, rich pore structure, larger specific surface area, abundant electrochemically active sites and Excellent double-layer capacitance effect, and nitrogen doping mainly exists in the active structure of graphitic nitrogen, pyrrolic nitrogen, and pyridine nitrogen, which is beneficial to adjust the electronic arrangement and electrochemical properties of carbon fibers. The abundant pseudocapacitance effect improves the actual specific capacitance of porous hollow carbon nanofibers, and the phosphorus-containing groups generated by phosphorus doping are beneficial to enhance the hydrophilicity of carbon nanofibers, promote the contact and wettability with the electrolyte, and make the electrical The chemically active sites are more fully exposed, enabling nitrogen- and phosphorus-doped porous hollow carbon nanofibers to have higher practical specific capacitance and cycling stability. |
