Example Embodiment
[0023] Example 1
[0024] 1) Add 0.7931gWCl 6 Add to 40mL of absolute ethanol to prepare 0.05mol / L solution A;
[0025] 2) Add 0.5390g analytically pure stearylamine (CH 3 (CH 2 ) 16 CH 2 NH 2 ) To obtain solution B;
[0026] 3) Seal solution B with plastic wrap to avoid contact with air, first stir with magnetic force for 20 minutes, and then ultrasonic (60 Hz) treatment for 30 minutes to obtain solution C;
[0027] 4) Add solution C to a 100mL autoclave lined with polytetrafluoroethylene, with a volume filling ratio of 40%, then seal the autoclave, and react in a homogeneous reactor at 160°C for 24 hours Cooled to room temperature with the furnace, centrifuged with absolute ethanol, washed 3 times, and dried in a vacuum drying oven at 60°C for 3 hours to obtain filamentous W 18 O 49 material.
[0028] by figure 1 It can be seen that the pure phase W of the product prepared by the present invention 18 O 49 material. by figure 2 It can be seen that the W obtained by the present inven...

[0030] Example 2
[0031] 1) Add 0.9914gWCl 6 Add to 50mL of absolute ethanol to prepare 0.06mol / L solution A;
[0032] 2) Add 0.6468g analytically pure octadecylamine (CH 3 (CH 2 ) 16 CH 2 NH 2 ) To obtain solution B;
[0033] 3) Seal the solution B with plastic wrap to avoid contact with air, first use magnetic stirring for 40 minutes, and then ultrasonic (60 Hz) treatment for 20 minutes to obtain solution C;
[0034] 4) Add solution C to a 100mL autoclave lined with polytetrafluoroethylene at a volume filling ratio of 40%, then seal the autoclave, and react in a homogeneous reactor at 150°C for 18h Cooled to room temperature with the furnace, centrifuged with absolute ethanol, washed 3 times, and dried in a vacuum drying oven at 60°C for 3 hours to obtain filamentous W 18 O 49 material.
[0035] The filamentary W obtained in this example 18 O 49 The single length is about 1~1.5μm.
Example Embodiment
[0036] Example 3
[0037] 1) Add 1.0259gWCl 6 Add it to 60mL of absolute ethanol to prepare 0.08mol / L solution A;
[0038] 2) Add 2.5870g analytically pure octadecylamine (CH 3 (CH 2 ) 16 CH 2 NH 2 ) To obtain solution B;
[0039] 3) Seal solution B with plastic wrap to avoid contact with air, first stir with magnetic force for 20 minutes, and then ultrasonic (60 Hz) treatment for 30 minutes to obtain solution C;
[0040] 4) Add solution C to a 100mL autoclave lined with polytetrafluoroethylene at a volume filling ratio of 60%, then seal the autoclave, and react in a homogeneous reactor at 170°C for 18 hours Cooled to room temperature with the furnace, centrifuged with absolute ethanol, washed 3 times, and dried in a vacuum drying oven at 60°C for 3 hours to obtain filamentous W 18 O 49 material.
[0041] The filamentary W obtained in this example 18 O 49 The single length is about 1.3~1.8μm.
