The invention provides a hollow porous carbon nanofiber with tin oxide loaded on the inner tube wall, a preparation method and application thereof. silk solution; dissolving polyvinylpyrrolidone and stannous chloride dihydrate to obtain core layer spinning solution; coaxial electrospinning of shell layer spinning solution and core layer spinning solution to obtain carbon fiber precursor; pre-oxidation and carbonization Compared with the porous carbon nanofibers prepared by the traditional method, the combination of tin oxide and carbon fibers forms a network skeleton, which not only makes the carbon fibers have more active sites and Higher specific capacitance, and its controllable ion and electron transport channels improve the stability and efficiency of tin oxide for storing charges, and the prepared hollow porous carbon nanofibers can be used in lithium batteries and supercapacitors. |
