Abstract

In this work, a one-step catalytic carbonization process was employed to convert MXene composite fibers with in situ grown ZIF-67 into an excellent substrate with an epitaxial structure (CNTs/PC-MX/CF). Subsequently, ultrathin MnO₂ nanosheets were deposited via electrodeposition, resulting in the formation of an MnO₂@CNTs/PC-MX/CF structure. The practical functionality of this structure was further validated by assembling an asymmetric device (ASC) based on MnO₂@CNTs/PC-MX/CF and CNTs/PC-MX/CF.
