Embodiment 1
[0024] Step 1. Take the discarded wet blue leather as a discarded leather sample, and use a solid-phase force chemical reactor to peel off the leather fibers at a pressure of 3 MPa, a rotating speed of 1000 rpm and room temperature; obtain micronano leather fibers with an average diameter of 1.2μm
[0025] Step 2: Place the obtained micro-nano leather fibers in a tube furnace, raise the temperature to a maximum temperature of 500°C at a heating rate of 5°C / min under an argon atmosphere, and keep it warm at the maximum temperature for 2 hours, and then heat it up with the furnace Cool to room temperature to obtain azacarbon fibers with an average particle size of 900 nm.
[0026] The obtained aza-carbon fiber was prepared into an electrode, and the specific capacitance of the electrode was tested to be 67 F / g at a current of 1 A / g.
[0027] The morphology and structure of nitrogen-doped carbon fibers obtained in this example are as follows: figure 2 shown by figure 1 and ...
