Abstract：ZIF-8-PAN composite nanofibers were prepared by electrospinning,and then ZIF-8-PAN derived porous carbon nanofibers(ZIF-8-PANC)were prepared by pre-oxidation and high-temperature carbonization.The morphology and microstruc-ture were characterized by scanning electron microscopy and the specific surface area,pore size distribution analysis,and their electrochemical properties for zinc ion hybrid supercapacitor(ZHS)were tested.The results show that ZIF-8-PANC combines the high conductivity of carbon nanofibers and the rich porous structure of ZIF-8 derived carbon,which not only provides good conductivity,but also realizes high specific surface area and hierarchical porous structure.Therefore,ZIF-8-PANC can effectively realize the rapid transfer of electrons,ions and the high-capacity storage of zinc ions.When the current density is 0.5 A·g-1,the specific capacity of the ZIF-8-PANC electrode reaches 240 mAh·g-1 and exhibits excellent cycle stability.
