Embodiment 1
[0030] The concentration of 1.2g carbon nanotubes in 250mL is 2.6mol / L HNO 3 solution, reflux at 140°C for 24 hours, then filter with suction, wash with water three times, and dry at 120°C for 24 hours. 0.1 g of acidified carbon nanotubes was taken out, and ultrasonically dispersed in 200 mL of 0.5 wt % tetramethylammonium hydroxide solution. 0.1 g of FePt nanoparticles was added to 200 mL of 0.5 wt % tetramethylammonium hydroxide solution ( FIG. 1 ), and ultrasonicated for 30 minutes. The above two solutions were mixed, sonicated for 30 minutes, and then stirred at room temperature for 12 hours. The obtained carbon nanotube dispersion solution (Fig. 3 and Fig. 4) can exist stably for more than 4 months, and the diameter of the carbon nanotube bundles is 2-3 nm (2-3 carbon nanotubes / bundle). The mass ratio of FePt nanoparticles to carbon nanotubes was changed to 2:1, 5:1, 10:1, 20:1 and the above process steps were repeated, and the obtained carbon nanotube dispersion soluti...
Embodiment 2
[0032] 1.0 g of carbon nanotubes were refluxed in 250 mL of 30% hydrogen peroxide solution at 120° C. for 4 hours, then suction filtered, washed with water three times, and dried at 120° C. for 24 hours. 0.2g carbon nanotubes were ultrasonically dispersed in 100mL 0.2wt% tetramethylammonium hydroxide solution. Add 0.5g CeO to 200mL 0.2wt% tetramethylammonium hydroxide solution 2 Nanoparticles (Figure 2), sonicated for 60 minutes. The above two solutions were mixed, sonicated for 30 minutes and stirred at room temperature for 36 hours. The diameter of the carbon nanotube bundles in the obtained carbon nanotube dispersion solution ( FIG. 6 ) was 10 nm (about 10 carbon nanotubes / bundle).
Embodiment 3
[0034] 0.1 g of acidified carbon nanotubes were ultrasonically dispersed in 200 mL of 0.3 wt % ammonia solution. 0.05 g of Au nanoparticles were added to 200 mL of 0.3 wt % ammonia solution, and ultrasonically dispersed for 30 minutes. The above two solutions were mixed, sonicated for 60 minutes and then stirred at room temperature for 72 hours. The diameter of the carbon nanotube bundles in the obtained carbon nanotube dispersion solution was 15 nm (about 15 carbon nanotubes / bundle).
