Embodiment 1
[0039] This example provides a nitrogen-sulfur co-doped graphene oxide grafted polyaniline / MoS 2 The preparation method of electrode specifically comprises the following steps:
[0040] 1) Preparation of nitrogen and sulfur co-doped graphene oxide
[0041] Add 1.3 g of graphene oxide, 5 g of sodium dodecylbenzenesulfonate and 300 mL of deionized water into a three-necked flask, and stir magnetically at room temperature to form a dispersion. Add 0.2g pyrrole, 0.1g thiophene and 1.8g FeCl to the dispersion 3 , continue to stir and react for 12 hours, and the product is filtered, washed and dried to obtain a graphene oxide / polypyrrole / polythiophene composite. Soak the complex in 100 mL of ammonium chloride solution with a mass concentration of 1.2% for 12 hours, wash and dry. The compound was put into a tube furnace, and under the protection of argon, the temperature was raised from 25°C to 270°C and kept for 2h, then the temperature was raised from 270°C to 780°C and kept for...
