[0014] The preparation method of ultra-thin carbon-coated tin dioxide nanocomposite material, the specific steps are as follows:
[0015] Weigh 0.018mol of tin tetrachloride, dissolve 1mol of glucose and 3mg of naphthalene in 60mL of deionized water, then add 0.8mL of hydrochloric acid, stir magnetically for 30min, put the resulting mixed solution in a kettle, and place it in a blast drying oven at 180°C for water. Thermal reaction, the reaction time is controlled at 12h. The product after the hydrothermal reaction was centrifugally washed and dried in a blast drying oven.
[0016] Then, the product obtained by the hydrothermal reaction was placed in a tube furnace, heat-treated in a nitrogen atmosphere, heated to 500 °C at a heating rate of 5 °C / min, and held for 4 h, thereby obtaining an ultra-thin carbon-coated tin dioxide nanocomposite. .
