Embodiment 1
[0020] 2.61 g (0.01 mol) BA (NO 3 ) 2 , 5.44g (0.01 mol) (NH 4 ) 2 B 10 O 6 · 8h 2 O, 60 ml of deionized water is added to 100 ml of high pressure reactor, and after stirring at room temperature, it is placed in a 160 ° C oven for 24 hours. After the reaction is completed, it is naturally cooled to room temperature, and the reaction product sequentially uses 60 to 80 ° C to distilled water, ethanol. After washing 2 ~ 3 times, 60 ° C is dried for 12 hours to get Bab 8 O 11 (OH) 4 Nanosheets.
[0021] The inventors use an X-ray diffractometer, and the scanning electron microscope characterizes the resulting sample. Figure 1 ~ 2 . Depend on figure 1 The XRD character is visible, and the diffraction data of the resulting material and Bab 8 O 11 (OH) 4 The diffraction data of JCPDS standard card (Fileno.97-042-1417) is consistent. Depend on figure 2 Visible, Bab 8 O 11 (OH) 4 The nano sheet is about 500 nm long, 150 to 200 nm wide, and the thickness is about 50 nm.
Embodiment 2
[0023] 2.61 g (0.01 mol) BA (NO 3 ) 2 8.16g (0.015 mol) (NH 4 ) 2 B 10 O 6 · 8h 2 O, 60 ml of deionized water is added to 100 ml of high pressure reactor, and after mixing at room temperature, the reaction is closed at 18 hours at 180 ° C, and after the reaction is completed, it is naturally cooled to room temperature, and the reaction product is sequentially washed with 60 ~ 80 ° C. After 2 ~ 3 times, 60 ° C is dried for 12 hours to get Bab 8 O 11 (OH) 4 Nano film (see image 3 .
Embodiment 3
[0025] 2.55 g (0.01 mol) BA (AC) 2 , 3.70g (0.058 mol) h 3 BO 3 10 ml of deionized water was added to 50 ml of high-pressure reactor, and after mixing at room temperature, it was mixed at 180 ° C for 12 hours, and naturally cooled to room temperature after completion, and the reaction product was sequentially washed with 60 to 80 ° C. ~ 3 times, 60 ° C drying 12 hours to get Bab 8 O 11 (OH) 4 Nano-belt. Depend on figure 1 The XRD character is visible, and the diffraction data of the resulting material and Bab 8 O 11 (OH) 4 JCPDS standard card (File No. 97-042-1417) diffraction data is consistent. Depend on Figure 4 Visible, Bab 8 O 11 (OH) 4 The nano-band thickness is about 50 nm.
