Embodiment 1
[0025] Embodiment 1: Preparation of nitrogen-doped carbon material
[0026] Step 1. At room temperature, dissolve 4 g of glucose, 5 g of melamine, and 3 g of zinc chloride in deionized water and stir for 3 hours to form a complex precipitate, then dry to obtain a carbonized precursor, and put it in a 100°C drying oven dry overnight;
[0027] Step 2. Put the material obtained in step 1 into a tube furnace after being ground, pass in an inert gas, and raise the temperature to 700°C at a heating rate of 5°C / min and keep it warm for 2 hours for carbonization. After cooling, take it out ;
[0028] In step 3, the nitrogen-doped carbon material containing metal ions is first washed with hydrochloric acid, then ethanol and deionized water, filtered, and vacuum-dried to obtain the nitrogen-doped porous carbon material CNC-3.
Embodiment 2
[0029] Embodiment 2: Preparation of nitrogen-doped carbon material
[0030] Step 1. At room temperature, dissolve 4g glucose, 5g melamine, and 1g zinc chloride in deionized water and stir for 3 hours to form a complex precipitate, then dry to obtain the carbonized precursor, and put it in a drying oven at 100°C for drying dry overnight;
[0031] Step 2. Put the material obtained in step 1 into a tube furnace after being ground, pass in an inert gas, and raise the temperature to 700°C at a heating rate of 5°C / min and keep it warm for 2 hours for carbonization. After cooling, take it out ;
[0032] In step 3, the nitrogen-doped carbon material containing metal ions is first washed with hydrochloric acid, then washed with ethanol and deionized water, filtered, and vacuum-dried to obtain the nitrogen-doped porous carbon material CNC-1.
Embodiment 3
[0033] Embodiment 3: Preparation of nitrogen-doped carbon material
[0034] Step 1. At room temperature, dissolve 4g of glucose and 5g of melamine in deionized water and stir for 3 hours to form a complex precipitate, then dry to obtain a carbonized precursor, and put it in a 100°C drying oven to dry overnight;
[0035] Step 2. Put the material obtained in step 1 into a tube furnace after being ground, pass in an inert gas, and raise the temperature to 700°C at a heating rate of 5°C / min and keep it warm for 2 hours for carbonization. After cooling, take it out ;
[0036] Step 3, the nitrogen-doped carbon material containing metal ions is first washed with hydrochloric acid, then washed with ethanol and deionized water, filtered, and vacuum-dried to obtain the nitrogen-doped porous carbon material CNC-0.
