Embodiment 1
[0025] (1) Measure 46mL concentrated H 2 SO 4 , 2g graphite powder and 1g NaNO 3 In a 500mL three-necked flask, sonicate for 30min, then transfer the mixture to a constant temperature water bath at 5°C and stir for 1h, then continue to add 6.5g KMnO to the three-necked flask 4 powder, continue to stir and react at 5°C for 4h, then raise the temperature to 38°C, stir for 30min, then raise the temperature to 95°C and stir for 30min, then add dilute H 2 SO 4 The solution terminates the reaction, removes the water bath, and obtains the primary product of graphite oxide (GO).
[0026] (2) Add dropwise 30mL H to the mixture in step (1) 2 o 2 To remove excess oxidant in the mixture, then the mixture was vacuum filtered, washed twice with 40mL dilute HCl, and then washed with 30mL HCl 2 o 2 Wash once, filter with suction, then disperse the solid in H 2 o 2 with H 2 In the mixed solution with O volume ratio of 1:5, ultrasonic stripping was performed for 2 h; a uniform and sta...
