Problems solved by technology

Both the thermal evaporation method and the high-temperature solid-state reaction method require very high temperatures (about 1000 ° C); the mechanical grinding method can only obtain irregular nanoparticles, and it is very difficult to prepare nanoparticles below 5 nanometers

Embodiment 1

[0012] 1.7408 grams of zinc chloride (ZnCl 2 , 0.0128 moles) and 2.2400 grams of tin chloride (SnCl 4 ·5H 2 O, 0.0064 mole) is put into 160 milliliters of deionized water, then adds 2.5600 grams of hydrazine hydrate (N 2 h 4 ·H 2 (2, 0.0512 moles), after stirring for 10 minutes, put the above-mentioned prepared solution into the polytetrafluoroethylene lining of the autoclave, and the lining volume is 200 milliliters, that is, the filling degree is 80%. The solution is treated at 250° C. for 24 hours, and the treated solution is centrifuged and dried to obtain ZTO nanorods of 2 to 4 nanometers. figure 1 is the XRD pattern of ZTO nanorods, and Zn 2 SnO 4 The standard card (JCPDS 74-2184) matches exactly. figure 2 is the TEM photo of ZTO nanorods, from figure 2 It can be seen that the obtained product is a single crystal ZTO nanorod of 2-4 nanometers.

Embodiment 2

[0014] 1.7408 grams of zinc chloride (ZnCl 2 , 0.0128 moles) and 2.2400 grams of tin chloride (SnCl 4 ·5H 2 O, 0.0064 mole) is put into 160 milliliters of deionized water, then adds 2.5600 grams of hydrazine hydrate (N 2 h 4 ·H 2 (2, 0.0512 moles), after stirring for 10 minutes, put the above-mentioned prepared solution into the polytetrafluoroethylene lining of the autoclave, and the lining volume is 200 milliliters, that is, the filling degree is 80%. The solution is treated at 300° C. for 24 hours, and the treated solution is centrifuged and dried to obtain ZTO nanorods of 3 to 5 nanometers. It can be seen that as the hydrothermal temperature rises, the crystal grows slightly. But when the hydrothermal temperature is lower than 250°C, the crystallization of the product is not good.

Embodiment 3

[0016] 1.7408 grams of zinc chloride (ZnCl 2 , 0.0128 moles) and 2.2400 grams of tin chloride (SnCl 4 ·5H 2 O, 0.0064 mole) is put into 160 milliliters of deionized waters, then adds 3.8400 grams of hydrazine hydrate (N 2 h 4 ·H 2 (2, 0.0768 moles), after stirring for 10 minutes, put the above-mentioned prepared solution into the polytetrafluoroethylene lining of the autoclave, and the lining volume is 200 milliliters, that is, the filling degree is 80%. The solution was treated at 250°C for 24 hours, and the treated solution was centrifuged and dried to obtain ZTO nanorods of 2 to 4 nanometers. The results were consistent with Example 1, indicating that the concentration of hydrazine hydrate had little effect on the product within a certain range. .

Abstract

A process for synthesizing the superfine (2-5 nm) spinel-type Zn2SnO4 nanorods features that hydrothermal reaction between zinc chloride as Zn source, tin chloride as Sn source and hydrazine hydrate as mineralizing agent.

Description

technical field [0001] The invention relates to a method for synthesizing spinel zinc stannate nanorods. Background technique [0002] Due to excellent properties and numerous potential applications, the nanostructures of ZnO and SnO in binary oxides have become a research hotspot in nanotechnology. Their ternary oxide - spinel zinc stannate (Zn 2 SnO 4 , referred to as ZTO) is also a wide bandgap semiconductor (bandgap width of about 3.6eV), due to its high electron mobility, high conductivity and low visible absorption, it is used in solar thin films, flammable gas detection, wet There are potential applications in many fields such as sensitive devices, photocatalysis, and electronic ceramics. ZTO nanostructures are likely to have better performance than zinc oxide and tin oxide nanostructures, but the current research on ZTO nanostructures is far from enough. . [0003] When the size of the nanostructure in a certain dimension is smaller than its excitonic Bohr radius...
