Embodiment 1
[0014] 100g SbCl 3 , 200g of oleic acid and 1000g of water are mixed into a precursor solution according to the mass ratio of 1:2:10, and placed in a hydrothermal reaction kettle for hydrothermal reaction. The hydrothermal reaction temperature is 200°C, and the constant temperature time is 24 hours; The final solid-liquid mixture was subjected to solid-liquid centrifugation, the liquid product was poured out, the solid product was taken out, washed twice with deionized water, and then dried at 90°C for 10 hours; the dried product was ground into powder to obtain Sb 8 o 11 Cl 2 submicron flakes.
[0015] figure 1 For the Sb prepared in Example 1 8 o 11 Cl 2 The transmission electron microscope figure (TEM) of submicron sheet; As can be seen therefrom, the Sb prepared by embodiment 1 8 o 11 Cl 2 Submicron flakes are submicron-sized, sheet-like structures. X-ray diffraction pattern (XRD) showed good crystallization.
Embodiment 2
[0017] 100g SbCl 3 , 500g oleic acid and 1000g water are mixed into a precursor solution according to the mass ratio of 1:5:10, and placed in a hydrothermal reaction kettle for hydrothermal reaction. The hydrothermal reaction temperature is 200 ° C, and the constant temperature time is 24 hours; the hydrothermal reaction The final solid-liquid mixture was subjected to solid-liquid centrifugation, the liquid product was poured out, the solid product was taken out, washed twice with deionized water, and then dried at 90°C for 10 hours; the dried product was ground into powder to obtain Sb 8 o 11 Cl 2 submicron flakes.
[0018] figure 2 For the Sb prepared in Example 2 8 o 11 Cl 2 The X-ray diffraction pattern (XRD) of submicron sheet; As can be seen therefrom, the Sb prepared by embodiment 2 8 o 11 Cl 2 Submicron flakes are pure Sb 8 o 11 Cl 2 Structure, good crystallization. Transmission electron microscopy (TEM) showed that the product was submicron in size and f...
Embodiment 3
[0020] 100g SbCl 3 , 400g oleic acid and 1000g water are mixed into a precursor solution according to the mass ratio of 1:4:10, and placed in a hydrothermal reaction kettle for hydrothermal reaction. The hydrothermal reaction temperature is 180°C, and the constant temperature time is 20 hours; the hydrothermal reaction The final solid-liquid mixture was subjected to solid-liquid centrifugation, the liquid product was poured out, the solid product was taken out, washed with deionized water for 3 times, and then dried at 85°C for 11 hours; the dried product was ground into powder to obtain Sb 8 o 11 Cl 2 submicron flakes. The product is similar in structure to Examples 1 and 2, both of submicron size, sheet-like structure, and good crystallization.
