Embodiment 1
[0027] The iron catalyst preparation process is as follows:
[0028] Dissolve 2.5 g of glucose and 3.05 g of ferric nitrate nonahydrate in 30 mL of deionized water, and stir vigorously. The resulting mixed solution was transferred to a 50mL hydrothermal synthesis reactor with a polytetrafluoroethylene liner. The reaction kettle is sealed and transferred to a hydrothermal synthesis device (also called an incubator). The condition control of the hydrothermal synthesis process is 120° C. for 20 hours. The obtained product distribution was repeatedly washed several times with deionized water and absolute ethanol. Finally, the product was dried for more than 12 hours, and it was taken out, which was recorded as Fe / C. The composite powder is obtained by mechanically mixing potassium chloride, calcium carbonate and magnesium oxide according to the weight ratio of K:Ca:Mg=3:1:0.3 by means of grinding. 1.0 g of Fe / C and 0.15 g of composite powder were mechanically mixed again by me...

[0032] The iron catalyst preparation process is as follows:
[0033] Dissolve 2.5 g of glucose and 3.05 g of ferric nitrate nonahydrate in 30 mL of deionized water, and stir vigorously. The resulting mixed solution was transferred to a 50mL hydrothermal synthesis reactor with a polytetrafluoroethylene liner. The reaction kettle is sealed and transferred to a hydrothermal synthesis device (also called an incubator). The condition control of the hydrothermal synthesis process is 120° C. for 20 hours. The obtained product distribution was repeatedly washed several times with deionized water and absolute ethanol. Finally, the product was dried for more than 12 hours, and it was taken out, which was recorded as Fe / C. 1.0 g of Fe / C and 0.15 g of potassium carbonate powder were mechanically mixed again by grinding, and the prepared catalyst was recorded as Fe / C-K.
[0034]K exists in the Fe / C-K catalyst as a separate electron aid. The ratio of each component is 14% (Fe), 3.7% (K...
