Embodiment 1
[0047] 1. Preparation of carbon-based catalyst supported by iron single atom: on the basis of synthesizing zinc oxide exposed to a special crystal plane (non-polar plane (1010)) supported by single atom iron, and 2-methylimidazole in an argon atmosphere In the high-temperature reaction in a tube furnace, the final catalyst is obtained in one step. Specifically:
[0048] (1) Weigh 0.407 g of iron-loaded zinc oxide and 0.977 g of 2-methylimidazole, and place them in a corundum boat with a cover of 2 cm*2 cm*10 cm, wherein the iron-loaded zinc oxide is placed in the middle of the corundum boat , corresponding to the downwind direction of the carrier gas; 2-methylimidazole is placed on the head of the corundum boat, corresponding to the upwind direction of the carrier gas.
[0049] (2) Put the corundum boat into the middle of a 4 cm*3mm*60cm quartz tube, then place the quartz tube in the tube furnace quartz tube, and place corundum plugs at both ends so that the corundum boat cor...
Embodiment 2
[0065] 1. Preparation of cobalt single-atom-supported carbon-based catalysts: On the basis of synthesizing single-atom cobalt-supported non-polar surface-exposed zinc oxide, and 2-methylimidazole in argon atmosphere in a tube furnace at high temperature reaction, the final catalyst is obtained in one step. Specifically:
[0066] (1) Weigh 0.407 g of cobalt-loaded zinc oxide and 0.977 g of 2-methylimidazole, and place them in a corundum boat with a cover of 2 cm*2 cm*10 cm, wherein the cobalt-loaded zinc oxide is placed in the middle of the corundum boat , corresponding to the downwind direction of the carrier gas; 2-methylimidazole is placed on the head of the corundum boat, corresponding to the upwind direction of the carrier gas.
[0067] (2) Put the corundum boat into the middle of a 4 cm*3mm*60cm quartz tube, then place the quartz tube in the tube furnace quartz tube, and place corundum plugs at both ends so that the corundum boat corresponds to the thermocouple position ...
