specific Embodiment approach 1
[0045] A preparation method of a paper-based mesoporous carbon electrode material, comprising the steps of:
[0046] Step 1. Weigh a certain quality of industrial filter paper, F127, 3-aminophenol, hexamethylenetetramine, 1,3,5-trimethylbenzene and distilled water, put the weighed material in a beaker and stir for 1 hour, Transfer to the reactor, set the reaction temperature to 180°C, and the reaction time to 12h, the reacted mixture is ready for use;
[0047] Step 2. Wash the mixture obtained after the reaction in step 1 with absolute ethanol and deionized water for 5 times, filter to obtain a filter paper with reddish-brown precipitate powder attached thereto, and place it in an oven to dry for 15 hours to obtain sample a for use ;
[0048] Step 3. Place the sample a obtained in step 2 in a tube furnace, carry out a temperature-programmed reaction under the protection of nitrogen, heat it from room temperature to 400°C at a heating rate of 2°C / min and keep it at the tempera...
