Embodiment 1
[0031] Embodiment 1: the preparation of Ag single-atom catalyst
[0032] Step 1, 1 g of aminated g-C 3 N 4 Add it to 20ml of anhydrous ether, add 0.25ml of 1.6M methyllithium ether solution dropwise to it under nitrogen atmosphere, stir while adding, keep the temperature of the system at -78°C during the dropwise addition, and place in nitrogen atmosphere after the dropwise addition Stir and react at 25°C for 8 hours, then filter, and the filter cake is washed and dried with anhydrous ether to obtain an intermediate product;
[0033] Step 2, disperse the obtained intermediate product and 65 mg AgCl in 20 ml of anhydrous ether under a nitrogen atmosphere, and stir and react at 25° C. for 8 hours to obtain a mixture of Ag single-atom catalyst and lithium chloride;
[0034] In step 3, the mixture described in step 2 is fully dissolved in water and then filtered, and the filter cake is dried at 50° C. to obtain the Ag single-atom catalyst with a loading capacity of 4%.

Embodiment 2
[0039] Embodiment 2: the preparation of Cu single-atom catalyst
[0040] Step 1, add 1g of hydroxylated fullerene to 20ml of anhydrous n-hexane, add 0.5ml of 2.5M n-butyl lithium ether solution dropwise to it under nitrogen atmosphere, stir while adding, and maintain the system during the dropping process The temperature is -78°C. After the dropwise addition, stir and reflux at 60°C under a nitrogen atmosphere for 6 hours, then filter, and the filter cake is washed and dried with anhydrous n-hexane to obtain an intermediate product;
[0041] Step 2, disperse the obtained intermediate product and 124 mg CuCl in 20 ml of anhydrous n-hexane under a nitrogen atmosphere, and stir and reflux at 60 ° C for 6 h to obtain a mixture of Cu single-atom catalyst and lithium chloride;
[0042] In step 3, the mixture described in step 2 is fully dissolved in water and then filtered, and the filter cake is dried at 100° C. to obtain the Cu single-atom catalyst with a loading capacity of 7%. ...
Embodiment 3
[0046] Embodiment 3: the preparation of Co single-atom catalyst
[0047] Step 1, add 1g of graphene oxide to 20ml of anhydrous furan, add 0.34ml of 16% tert-butyl lithium pentane solution dropwise to it under nitrogen atmosphere, stir while adding, and maintain the system temperature at -78°C during the dropping process °C, after the dropwise addition, stir and reflux at 80 °C for 4 hours under a nitrogen atmosphere, then filter, and the filter cake is washed and dried with anhydrous furan to obtain an intermediate product;
[0048] Step 2, the intermediate product obtained with 66mg CoCl 2 Disperse in 20ml of anhydrous furan under a nitrogen atmosphere, stir and reflux at 80°C for 4h to obtain a mixture of Co single-atom catalyst and lithium chloride;
[0049] In step 3, the mixture described in step 2 is fully dissolved in water and then filtered, and the filter cake is dried at 150° C. to obtain the Co single-atom catalyst, wherein the loading amount is 2%.
