Preparation method of a core-shell Fe2O3@PPy composite and its application in supercapacitors |
abstract |
The invention relates to a preparation method of a hollow core-shell structure Fe 2 O 3 @PPy composite material and its application in a supercapacitor, belonging to the technical field of supercapacitors. First, MnO 2 nanotubes were prepared, and Fe 2 O 3 nanotubes were obtained by redox reaction with MnO 2 nanotubes as templates, and then a layer of conductive PPy was uniformly coated on the Fe 2 O 3 nanotubes through chemical oxidation polymerization to obtain Fe2O3 @PPy nanotubular composites with hollow core - shell structure. This composite material exhibits excellent electrochemical performance when used as a supercapacitor anode, with an areal specific capacitance as high as 530 mF/cm -2 . |
