Embodiment 1
[0046] (1) Disperse 3 g of carbon nanotubes in 100 mL of concentrated sulfuric acid-concentrated nitric acid (volume ratio of 2:1) mixed solution, stir and react at 80°C for 8 hours to obtain an acid-treated carbon nanotube mixed acid solution;
[0047] (2) After the carbon nanotube mixed acid solution is cooled to room temperature, it is centrifuged, washed twice with deionized water and ethanol each, and dried in a vacuum oven at 50°C to obtain acid-treated carbon nanotube powder;
[0048] (3) Disperse 50 mg of acid-treated carbon nanotube powder in 25 mL of N,N-dimethylformamide and sonicate for a period of time to obtain an organic dispersion of carbon nanotubes;
[0049] (4) Dissolve 50 mg of selenium powder in 25 mL of hydrazine hydrate and stir for a period of time to make it evenly dispersed;
[0050] (5) Dissolve 76.61 mg of sodium molybdate in 0.2 mL of water, dissolve it fully by ultrasound and make it evenly dispersed;
[0051] (6) Pour the mixed solution containing carbon n...
