Embodiment 1

[0016] Weigh 0.6 g of dioctyltin oxide, 0.1 g of graphene, and 0.2 g of sublimed sulfur according to the mass ratio of 6:1:2. After the three substances are fully mixed for 10 minutes, press the mixture into several pieces with a thickness of 1 mm and a diameter of 1 cm. The discs were then placed in a crucible and calcined in a muffle furnace at 480° C. for 2 hours to obtain tin dioxide microflakes with hexagonal morphology.

[0017] See figure 1 , figure 1 The positions and intensities of the main diffraction peaks are in good agreement with the standard card of tin dioxide, indicating that the main component of the product is tin dioxide.

[0018] See figure 2 ,from figure 2 It can be seen from the photo that the prepared sample is composed of flake particles with hexagonal morphology, the surface of each flake is very smooth, and each flake can exist independently or interlaced with each other. The length of each piece is about 1 μm, the width is about 0.6 μm, and th...

Embodiment 2

[0020] Weigh 0.7 g of dibutyltin diacetate, 0.1 g of graphene, and 0.2 g of sublimed sulfur according to the mass ratio of 7:1:2. After the three substances are fully mixed for 10 minutes, press the mixture into several pieces with a thickness of 1 mm and a diameter of 1 cm discs, and then put the pressed discs in a crucible and calcined in a muffle furnace at 550°C for 2 hours to obtain tin dioxide microflakes with hexagonal morphology.

Embodiment 3

[0022] Weigh 0.9 g of dioctyltin oxide, 0.1 g of graphene, and 0.2 g of sublimed sulfur according to the mass ratio of 9:1:2. After the three substances are fully mixed for 10 minutes, press the mixture into several pieces with a thickness of 1 mm and a diameter of 1 cm. The discs were then placed in a crucible and calcined in a muffle furnace at 580° C. for 1.5 hours to obtain tin dioxide microflakes with hexagonal morphology.

Abstract

The invention discloses a preparation method of a tin dioxide micron sheet with a hexagonal profile. A preparation process includes the steps: one of compounds of di-n-octyltin oxide and dibutyltin diacetate is selected to be mixed with graphene and sublimed sulfur, after tabletting, calcination is conducted for certain time at a certain temperature, and thus the tin dioxide micron sheet with thehexagonal profile is obtained. The method is simple, easy to operate and low in cost. The obtained tin dioxide micron sheet with the special profile has potential application prospects in micron devices.

Description

technical field [0001] The invention relates to a preparation method of tin dioxide microsheets with hexagonal morphology, belonging to the technical field of energy materials. Background technique [0002] It is well known that by SnO 2 The formed gas sensor has the advantages of simple structure, high sensitivity, good selectivity, and long service life, and is widely used in the detection of various flammable, explosive, and harmful gases. At the same time, SnO 2 Coatings have been widely used in the electrochemical treatment of industrial wastewater and domestic sewage because of their high catalytic activity, low cost and easy availability. In addition, tin oxide is considered to be an important material that is most likely to replace graphite, the anode material of lithium batteries, due to its advantages of high specific capacity, low lithium intercalation potential and low price. At the same time, it was found that there is an extremely close correlation between t...
