Embodiment 1
[0037] The preparation process of ultrathin Prussian blue analog nanosheet catalyst (2D CoFe-PBA@NF-24) is as follows:
[0038] 1) Cut blank nickel foam (1cm×2cm) and use acetone, ethanol, and deionized water to sonicate for 15 minutes respectively to remove surface pollutants, and put it in a 60°C oven for 6 hours before using it as a substrate.
[0039] 2) 100mL Co(NO 3 ) 2 ·6H 2 O (3mmol) aqueous solution was added to 100mL Na 2 Fe(CN) 5 NO·H 2 O (1 mmol) aqueous solution, the resulting solution was stirred at room temperature for 1 min until the solution became cloudy. Put the treated foamed nickel substrate into it, and let it stand in a dark place at room temperature for 24 hours. Finally, the nickel foam obtained by the reaction was rinsed with deionized water, and dried in an oven at 60°C for 12 hours to obtain the product 2D CoFe-PBA@NF-24.
[0040] When the 2D CoFe-PBA@NF-24 electrocatalyst prepared in this example is used to catalyze the hydrogen evolution re...
Embodiment 2
[0054] In this example, when Co(NO 3 ) 2 ·6H 2 O solution and Na 2 Fe(CN) 5 NO·H 2 After the O solution was mixed, the nickel foam substrate was put into the mixed solution, and left to react for 2 hours at room temperature in the dark, and the rest was the same as in Example 1 to prepare a 2D CoFe-PBA@NF-2 electrocatalyst.
Embodiment 3
[0056] In this example, when Co(NO 3 ) 2 ·6H 2 O solution and Na 2 Fe(CN) 5 NO·H 2 After the O solution was mixed, the nickel foam substrate was put into the mixed solution, and left to react for 12 hours at room temperature in the dark, and the rest was the same as in Example 1 to prepare a 2D CoFe-PBA@NF-12 electrocatalyst.
