Conditions

Temperature
70 °C

Procedure

50 mg of graphene oxide was added into 0.06 M p-aminobenzene sulfonic acid solution, and the resulted solution was heated to 70° C. Then, 2 ml of 6×10−3 M NaNO2 solution was dropped slowly into the resulted solution while stirring, and the resulted solution was allowed to react at 70° C. for 12 hours. After the reaction was completed, the resulted solution was cooled, filtrated and washed with pure water until the powder was neutral, and thus graphite sulfonate (GO-Ph-SO3H) dispersion solution was obtained.
