Embodiment 1
[0033] (1) Anode treatment: Ultrasonic cleaning of 1 square centimeter tantalum foil with acetone and ethanol, respectively, to remove organic matter on the surface, and blow dry with nitrogen; use a circular tantalum foil with an exposed surface diameter of 0.5 square centimeters and an area of 0.19625 square centimeters as Anode, 0.27mol / L NH 4 F and 15.89 mol / L H 2 SO 4 As the electrolyte, the platinum sheet was used as the cathode, and anodized at a voltage of 60 V for 15 minutes. After the reaction, the sample was rinsed with flowing distilled water and dried with nitrogen to obtain porous anodized tantalum oxide;
[0034] (2) Confined growth of iron oxide and nickel oxide in the channels of tantalum oxide nanoarrays: 0.028gNiCl 2 ·6H 2 O, 0.048gFe(NO 3 ) 3 9H2 O and 0.03gCO(NH 2 ) 2 dissolved in 4mlH 2 In O, sink the magnetic stirring bar to the bottom of the solvent, place the porous tantalum oxide obtained in step (1) in a cubic copper cage and suspend it in...
Embodiment 2
[0038] (1) Anode treatment: Ultrasonic cleaning of 1 square centimeter tantalum foil with acetone and ethanol, respectively, to remove organic matter on the surface, and blow dry with nitrogen gas; a circular tantalum foil with an exposed surface diameter of 0.5 square centimeters and an area of 0.19625 square centimeters was used as Anode, 0.27mol / L NH 4 F and 15.89 mol / L H 2 SO 4 Electrolyte, platinum sheet as cathode, anodized at 60 V for 15 min. After the reaction, the sample was rinsed with flowing distilled water and dried with nitrogen to obtain porous anodized tantalum oxide;
[0039] (2) Confined growth of iron oxide and nickel oxide in the channels of tantalum oxide nanoarrays: 0.028gNiCl 2 ·6H 2 O, 0.048gFe(NO 3 ) 3 9H 2 O and 0.03gCO(NH 2 ) 2 dissolved in 4mlH 2 In O, sink the magnetic stirring bar to the bottom of the solvent, place the porous tantalum oxide obtained in step (1) in a cubic copper cage and suspend it in the upper part of the solvent, mi...
