Embodiment 1
[0056] A kind of preparation method of anatase type nano-titanium dioxide comprises the steps:
[0057] (1) TiCl 4 Dispersed in ethanol to prepare the precursor, in which TiCl 4 The molar ratio with ethanol is 1:5;
[0058] (2) Raise the precursor to 150°C at a heating rate of 8°C / min, and perform solvothermal treatment for 2 hours to prepare a material system containing titanium dioxide;
[0059] (3) The material system containing titanium dioxide is washed with ethanol, centrifuged at a speed of 10000r / min for 10min and dried at 60°C for 3h to obtain anatase nano-titanium dioxide. figure 1 It is the XRD characterization spectrum of the anatase nano-titanium dioxide. It can be seen from the figure that the characteristic peak of titanium dioxide is sharp and has no miscellaneous peaks, indicating that the crystallization is relatively pure anatase-type nano-titanium dioxide. figure 2 with image 3 For the TEM characterization collection of described anatase nano-titanium...
Embodiment 2
[0061] The difference with Example 1 is that in step (1) TiCl 4 The molar ratio with ethanol is 1:1, and the anatase nano-titanium dioxide is prepared.
Embodiment 3
[0063] The difference with Example 1 is that in step (1) TiCl 4 The molar ratio of ethanol to ethanol is 1:20 to prepare anatase nano-titanium dioxide.
