Embodiment 1
[0051] (1) Preparation of layered graphite oxide:
[0052] First, 74 g of concentrated sulfuric acid with a mass concentration of 98% was added to a dry beaker with a volume of 250 mL at room temperature, and placed in an ice-water bath to cool to 0 °C; then 1 g of sodium nitrate powder was added to the beaker and stir to dissolve the sodium nitrate, then add 2 g of natural flake graphite with an average particle size of 0.5 μm, stir and react for 60 min, and keep the temperature of the reaction system not exceeding 5 °C; then slowly add 0.3 g of potassium permanganate powder into the beaker and fully react for 30 min, while keeping the temperature of the reaction system not higher than 10 °C, then slowly add 5.7 g of potassium permanganate powder into the above mixed solution in three batches within 1 h, and control the temperature of the mixed solution so that it does not over 20°C; then remove the cold bath, heat the temperature of the reaction system to 27°C with a water b...
