Examples
Embodiment 1
[0043] (1) Mix 70g of nano-titanium dioxide powder, 25g of activated carbon powder and 1g of glucose, place them in a ball mill jar, and perform ball milling for 10 hours with a ball-to-material ratio of 10:1 to obtain a mixed powder;
[0044] (2) Put the mixed powder in an atmosphere furnace, and heat treat the mixed powder under a nitrogen atmosphere. The heat treatment temperature is 1200°C, the heating rate is 8°C / min, and the holding time is 1h. After the reaction time expires, follow the furnace Cool down to get Ti 4 o 7 nanomaterials.
[0045] The Ti that the embodiment of the present invention 1 obtains 4 o 7 The X-ray diffraction pattern of the material is as figure 1 shown by figure 1 It can be seen that only Ti appears in the X-ray diffraction spectrum of the nanomaterial obtained by the preparation method of Example 1. 4 o 7 Diffraction peaks of the crystal structure, indicating that the main component of the nanomaterials is Ti 4 o 7 .
Embodiment 2
[0047] (1) Mix 60g of nano-titanium dioxide powder, 20g of carbon black powder and 0.3g of epoxy resin, place in a ball mill jar, and carry out ball milling for 40h with a ball-to-material ratio of 5:1 to obtain a mixed powder;
[0048] (2) Put the mixed powder in an atmosphere furnace, and heat treat the mixed powder under an argon atmosphere. The heat treatment temperature is 950°C, the heating rate is 15°C / min, and the holding time is 4h. Cool down the furnace to get Ti 4 o 7 nanomaterials.
Embodiment 3
[0050] (1) Mix 79.5g of nano-titanium dioxide powder, 20g of graphite powder and 0.5g of citric acid, place in a ball mill jar, and carry out ball milling for 20h with a ball-to-material ratio of 10:1 to obtain a mixed powder;
[0051] (2) Put the mixed powder in an atmosphere furnace, and heat-treat the mixed powder under a helium atmosphere. The heat treatment temperature is 1100°C, the heating rate is 10°C / min, and the holding time is 2h. Cool down the furnace to get Ti 4 o 7 Material.
