29/01/2020  It consists of carrying out a reaction of graphite powder with KMnO 4 and NaNO 3 in concentrated H 2 SO 4. They used H 2 SO 4 to disperse graphite and a mixture of KMnO 4 and NaNO 3 as oxidant agent; the temperature was kept below 45 °C and the reaction time was just a few minutes long. Basically, the reaction took place in an acid solution and the addition of hydrogen peroxide (H 2
