Embodiment 1
[0027] Take a purchased 200nm aluminum oxide film 3 and place it in the middle of two quartz reaction cells 1, and inject a concentration of 0.08mol / L CoSO into one quartz reaction cell 4 Solution 2, inject 10g / L sodium borohydride aqueous solution 4 into another quartz reaction cell, let it stand for 8 minutes at room temperature, take off the black nanotube / alumina composite film, and then clean the composite film with distilled water and absolute ethanol 3- 4 times, put into a vacuum drying oven at room temperature and dry to constant weight, partially dissolve with 2mol / L NaOH and use a scanning electron microscope to detect the topography of the nanotube array ( image 3 ); immerse in 2mol / L NaOH for 48 hours until the aluminum oxide film is completely dissolved, then centrifugally wash with distilled water until the pH is neutral, and finally rinse twice with absolute ethanol, put it in a vacuum drying oven at room temperature and dry to constant weight, then Amorphous m...
Embodiment 2
[0029] Take a piece of purchased 200nm aluminum oxide film and place it in the middle of two quartz reaction cells, and one quartz reaction cell is injected with a concentration of 0.06mol / L NiSO 4 Solution, inject 8g / L sodium borohydride aqueous solution into another quartz reaction tank, let it stand for 10 minutes at room temperature, remove the black nanotube / alumina composite film, and then wash the composite film with distilled water and absolute ethanol for 3-4 times , put into a vacuum drying oven at room temperature and dry to constant weight, partially dissolve with 2mol / L NaOH, and use a scanning electron microscope to detect the topography of the nanotube array ( Figure 4 ); immerse in 2mol / L NaOH for 48 hours until the aluminum oxide film is completely dissolved, then centrifugally wash with distilled water until the pH is neutral, and finally rinse twice with absolute ethanol, put it in a vacuum drying oven at room temperature and dry to constant weight, then Am...
Embodiment 3
[0032] Take a piece of purchased 200nm aluminum oxide film and place it in the middle of two quartz reaction cells. One quartz reaction cell is injected with a concentration of 0.05mol / L FeSO 4 Solution, inject 5g / L sodium borohydride aqueous solution into another quartz reaction tank, let it stand at room temperature for 12 minutes, remove the black nanotube / alumina composite film, and then wash the composite film with distilled water and absolute ethanol for 3-4 times , put into a vacuum drying oven at room temperature and dry to constant weight, partially dissolve with 2mol / L NaOH, and use a scanning electron microscope to detect the topography of the nanotube array ( Figure 5 ); immerse in 2mol / L NaOH for 48 hours until the aluminum oxide film is completely dissolved, then centrifugally wash with distilled water until the pH is neutral, and finally rinse twice with absolute ethanol, put it in a vacuum drying oven at room temperature and dry to constant weight, then Amorph...
