Embodiment 1
[0021] 1) Anodic oxidation of carbon nanomaterials: Dissolve 6.94mL of concentrated sulfuric acid in 50mL of distilled water, and add a certain amount of distilled water to a 250mL volumetric flask to obtain a clear electrolyte; use a graphite rod (size D5×100mm ) as the anode, graphite sheet (size 10×2×100mm) as the cathode, fix it in a beaker with 250mL sulfuric acid electrolyte with a test tube clamp, put it in a magnetic stirrer and place it on a magnetic stirrer, turn on the power, adjust DC stable power supply, the initial voltage is 4.0V.
[0022] 2) Filtration: When the graphite rod is consumed to the remaining 1 / 5, the solution of dissolved graphite powder is left to settle, the supernatant is poured off and rinsed with distilled water, after standing still, rinsed again, after repeated rinsing, use pH test paper Measure the acidity and alkalinity of the solution until it is nearly neutral.
[0023] 3) Reduction: Weigh 1 g of sodium hydroxide and dissolve it in 1000 ...
