Embodiment 1
[0026] Zn(CH 3 COO) 2 、GeO 2 , KCl and LiCl were mixed in a ratio of 2:1:120:24, and ground with an agate mortar to obtain a uniformly mixed solid mixture; the obtained mixture was collected in an alumina crucible and then placed in a muffle furnace , heated up to 540°C at a rate of 5°C / min, roasted for 6 hours, and cooled naturally; soaked the reacted product in deionized water to remove salt, and filtered it with suction to obtain an off-white solid; the obtained off-white solid was taken out into a centrifuge tube, Centrifuge and wash with deionized water for several times, and vacuum dry at 60°C to obtain Zn 2 GeO 4 Nano stave.
[0027] Analyze the crystal structure and chemical composition of samples by X-ray diffraction, such as figure 1 As shown, the results show that the product is Zn 2 GeO 4 Pure phase compound, no other impurities present.

Embodiment 2
[0030] Zn(CH 3 COO) 2 、GeO 2 , KCl and LiCl were mixed in a ratio of 2:1:120:24, and ground with an agate mortar to obtain a uniformly mixed solid mixture; the obtained mixture was collected in an alumina crucible and then placed in a muffle furnace , heated up to 660°C at a rate of 5°C / min, roasted for 6 hours, and cooled naturally; soaked the reacted product in deionized water to remove salt, and filtered it with suction to obtain an off-white solid; the obtained off-white solid was taken out into a centrifuge tube, Centrifuge and wash with deionized water for several times, and vacuum dry at 60°C to obtain Zn 2 GeO 4 Nano stave.
[0031] image 3 Is the Zn prepared in this example 2 GeO 4 Scanning electron microscope photo of the sample, it can be seen that the synthesized product is Zn 2 GeO 4Nanorods with a diameter of 60-300 nm and a length of 300-1500 nm.
Embodiment 3
[0033] ZnO, GeO 2 , KCl and LiCl are mixed according to the ratio of the amount of substances 2:1:60:12, ground with an agate mortar, and mixed uniformly to obtain a solid mixture; the obtained mixture is collected in an alumina crucible and then put into a muffle furnace, Heat up to 780°C at a rate of 5°C / min, roast for 4 hours, and cool naturally; impregnate the reacted product with deionized water to remove salt, filter with suction, and obtain an off-white solid; take the off-white solid out to a centrifuge tube, and use Centrifugal washing several times with deionized water, vacuum drying at 60°C to obtain Zn 2 GeO 4 Nano stave.
[0034] Figure 4 Is the Zn prepared in this example 2 GeO 4 Scanning electron microscope photo of the sample, it can be seen that the synthesized product is Zn 2 GeO 4 Nanorods with a diameter of 200-500 nm and a length of 400 nm-1400 nm.
