specific Embodiment 1
[0022] (1) On the basis of the soft template self-assembly method, mix 1g of surfactant F127, 0.5mL of furfuryl alcohol, 0.001mol of ferric chloride and 1g of ethyl orthosilicate;
[0023] (2) Transfer the mixture to a flat-bottomed evaporating dish, evaporate the solvent overnight at room temperature, put it in an oven at 70°C for thermal polymerization for 24 hours, and form a tan film;
[0024] (3) Scrape it off and put it into a porcelain boat for carbonization. Carbonization is carried out in an atmosphere tube furnace with a nitrogen gas flow, and the temperature is kept at 350°C for 3 hours, and at 500°C for 2 hours, and the heating rate is strictly controlled at 1°C / min;
[0025] (4) Label the product in the form of CS-xFe-y, wherein x represents the amount of the substance added with iron salt (mmol), and y represents the calcination temperature, and the sample is named CS-Fe-500.
[0026] The method is simple and easy, and the preparation cost is low. In the obtaine...

specific Embodiment 3
[0032] (1) On the basis of the soft template self-assembly method, mix 1g of surfactant F127, 0.5mL of furfuryl alcohol, 0.002mol of ferric chloride and 1g of ethyl orthosilicate;
[0033] (2) Transfer the mixture to a flat-bottomed evaporating dish, evaporate the solvent overnight at room temperature, put it in an oven at 120°C for thermal polymerization for 24 hours, and form a tan film;
[0034] (3) Scrape it off and put it into a porcelain boat for carbonization. Carbonization is carried out in an atmosphere tube furnace with a nitrogen gas flow, and the temperature is kept at 350°C for 3 hours, and at 700°C for 2 hours, and the heating rate is strictly controlled at 1°C / min;
[0035] (4) Label the product in the form of CS-xFe-y, wherein x represents the amount of the substance added with iron salt (mmol), and y represents the calcination temperature. The sample is named CS-2Fe-700.
[0036] This method is simple and easy to implement, and the preparation cost is low. ...
