Embodiment 1
[0040] Add 2 grams of nitric acid into a 100mL round-bottomed flask containing 6 grams of hydrochloric acid, add 0.2 gram of molybdenum disulfide powder, install a straight condenser tube in the round-bottomed flask, and put on a tail gas absorption device, and drain the tail gas with water Absorption, to avoid exhausting the tail gas directly into the air, use an oil bath to heat, raise the oil bath to 110°C, and keep it for 30 minutes. After the reaction is completed, add 30mL deionized water to dilute the reaction solution, and then use centrifugation to separate the product Separated and washed three times with deionized water and once with isopropanol, finally the resulting product was dispersed in 2 g of isopropanol. The SEM figure, TEM figure, HTEM figure, lattice electron diffraction figure of the flaky nano-molybdenum disulfide prepared by the present embodiment and the following examples are respectively as follows Figure 2-5 shown. Compare the SEM images of the mo...
Embodiment 2
[0042] Add 2 grams of nitric acid into a 100mL round-bottomed flask containing 6 grams of hydrochloric acid, add 0.2 gram of molybdenum disulfide powder, install a straight condenser tube in the round-bottomed flask, and put on a tail gas absorption device, and drain the tail gas with water Absorption, to avoid exhausting the tail gas directly into the air, place the reaction bottle in an ultrasonic generator, and perform ultrasonication. The temperature of the water bath is set to 50°C, and ultrasonication is performed for 20 minutes. The product was then separated by centrifugation, washed three times with deionized water and once with isopropanol, and finally the obtained product was dispersed in 2 g of isopropanol.
Embodiment 3
[0044] Add 3 grams of nitric acid into a 100mL round-bottomed flask containing 6 grams of hydrochloric acid, add 0.2 gram of molybdenum disulfide powder, install a straight condenser tube in the round-bottomed flask, and put a tail gas absorption device on it. Absorption, to avoid exhausting the tail gas directly into the air, use an oil bath to heat, raise the oil bath to 110°C, and keep it for 30 minutes. After the reaction is completed, add 30mL deionized water to dilute the reaction solution, and then use centrifugation to separate the product Separated and washed three times with deionized water and once with isopropanol, finally the resulting product was dispersed in 2 g of isopropanol.
