Embodiment 1
[0018] Example 1: A preparation of mesoporous carbon and FeS with waste fungus chaff 2 The method for composite electrode material is specifically completed according to the following steps:
[0019] 1. Pretreatment of carbon source: Take 50 g of waste fungus chaff, crush it, add 80 mL of 1.0 mol / L hydrochloric acid, sonicate at a frequency of 30 kHz for 60 min, filter and wash with distilled water, dry at 50°C, and then add 0.5 mol / LCoCl 2 The solution was 80 mL, stirred at a constant speed for 60 min, and dried under vacuum at 40°C to control the waste fungus chaff and CoCl 2 The mass ratio is 10:1;
[0020] 2. Preparation of mesoporous carbon: put the sample obtained in step 1 into a tube furnace, and in a nitrogen atmosphere, first raise the temperature to 300°C for 1 hour, then raise the temperature to 800°C for 3 hours, cool to room temperature, and add 1mol / L hydrochloric acid The solution was 50mL, stirred at 50r / min for 3 hours, filtered under reduced pressure, wash...
