Embodiment 1
[0035](1) First, 1.1 mmol of fumaric acid was dissolved in 10 mL of deionized water, and stirred at 400 rpm for 10 min at 60°C. Then, 1.3mmol of Fe(NO 3 ) 3 9H 2 O was added to the solution and stirred for another 10 min. Finally, the solution was transferred to a polytetrafluoroethylene stainless steel autoclave (total capacity 40 mL) and kept at 100 °C for 5 h.
[0036] (2) After cooling to room temperature, the MIL-88A hexagonal nanorods obtained by centrifugation were washed with deionized water and ethanol, and finally dried in a vacuum oven.
[0037] (3) The synthesized MIL-88A nanorods were transferred to a tube furnace and 2 carbonization in the atmosphere. Specifically, the material was heated at 2 °C min -1 The heating rate was heated from room temperature to 500°C and kept for 2h.
[0038] (4) 30 mL of hydrazine hydrate containing 100 mg of carbonized MIL-88A hexagonal nanorods and 100 mg of selenium powder was placed in an oil bath at 75° C. and stirred for ...
Embodiment 2
[0041] (1) First, 1.2 mmol of fumaric acid was dissolved in 25 mL of deionized water, and stirred at 400 rpm for 10 min at 70°C. Then, 1.3mmol of Fe(NO 3 ) 3 9H 2 O was added to the solution and stirred for another 10 min. Finally, the solution was transferred to a polytetrafluoroethylene stainless steel autoclave (total capacity 40 mL) and kept at 110 °C for 6 h.
[0042] (2) After cooling to room temperature, the MIL-88A hexagonal nanorods obtained by centrifugation were washed with deionized water and ethanol, and finally dried in a vacuum oven.
[0043] (3) The synthesized MIL-88A nanorods were transferred to a tube furnace and 2 carbonization in the atmosphere. Specifically, the material was heated at 2 °C min -1 The heating rate was heated from room temperature to 600°C and kept for 2h.
[0044] (4) 40 mL of hydrazine hydrate containing 100 mg of carbonized MIL-88A hexagonal nanorods and 100 mg of selenium powder was placed in an oil bath at 90° C. and stirred for...
Embodiment 3
[0055] (1) Firstly, 1.3 mmol of fumaric acid was dissolved in 30 mL of deionized water, and stirred at 80° C. at 400 rpm for 30 min. Then, 1.3mmol of Fe(NO 3 ) 3 9H 2 O was added to the solution and stirred for another 10 min. Finally, the solution was transferred to a polytetrafluoroethylene stainless steel autoclave (total capacity 40 mL) and kept at 110 °C for 6 h.
[0056] (2) After cooling to room temperature, the MIL-88A hexagonal nanorods obtained by centrifugation were washed with deionized water and ethanol, and finally dried in a vacuum oven.
[0057] (3) The synthesized MIL-88A nanorods were transferred to a tube furnace and 2 carbonization in the atmosphere. Specifically, the material was heated at 2 °C min -1 The heating rate was heated from room temperature to 600°C and kept for 3h.
[0058] (4) 50 mL of hydrazine hydrate containing 100 mg of carbonized MIL-88A hexagonal nanorods and 120 mg of selenium powder was placed in an oil bath at 95° C. and stirred...
