Embodiment

[0012] Add 0.054g of stannous sulfate into 50ml of ionized water, then transfer the aqueous solution of stannous sulfate into a stainless steel reaction kettle with a polytetrafluoroethylene substrate, conduct a hydrothermal reaction at 200°C for 1 day, and wash and filter the obtained product with deionized water 3 times, drying at 70°C for 4 hours to obtain high-purity SnO composed of nanorods 2 nano hollow spheres.

[0013] From figure 1 It can be seen from the scanning electron microscope that the as-prepared SnO 2 It is a spherical structure composed of many fine nanorods, and these spherical structures are aggregated together. figure 2 The TEM further confirmed such a structure. From figure 2 It can be observed that these spherical structures are hollow and about 200 nm in diameter. On the spherical shells of these hollow spheres are some SnO with a diameter of about 5-10nm and a length of tens of nanometers. 2 Nano stave.

Abstract

The invention provides a method for preparing a tin dioxide nano hollow sphere comprising nano rods and application in a lithium battery. The method for preparing the nano hollow sphere comprises thefollowing concrete steps: adding stannous sulfate into 50 ml of ionized water; then filling stannous sulfate aqueous solution into a stainless steel reaction vessel with a polytetrafluoroethylene substrate to carry out hydrothermal reaction at 200 DEG C for one day; washing and filtering the obtained product for three times by deionized water, drying at 70 DEG C for four hours and obtaining the high-purity nano hollow sphere which comprises the nano rods and is used for the lithium ion battery and a gas sensor or a solar energy electrical nano hollow sphere comprising the nano rods. The methodhas simple and convenient operation, low cost, high purity, favorable performance and no pollution.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials and their applications, and more specifically relates to the preparation of tin dioxide nano hollow spheres composed of nanorods and their application in lithium batteries. Background technique [0002] As an important semiconductor material, tin dioxide has good photoelectric properties, and is widely used in the production of electronic components, enamel pigments, tin salt manufacturing, marble and glass polishing agents, and the manufacture of opaque glass, antifreeze glass and High-strength glass and more. In recent years, tin dioxide nanomaterials (such as nanobelts, nanowires, nanoparticles, and hollow spheres) have been widely studied and deserved, and the preparation methods are also various, but they are all cumbersome. There is no report on the preparation of tin dioxide hollow nanospheres composed of nanorods and related patents on their applications. Contents of the invention...
