NOVELTY - Synthesizing reduced graphene oxide (RGO)-gold complex nano materials comprises (i) taking quantitative sodium acetate, adding water to dissolve, using glacial acetic acid to adjust the pH value to 5-6.5, and adding water to dilute, (ii) using the above buffer solution as a solvent to prepare a concentration of 0.1-10 mg/ml chitosan solution A, (iii) preparing the reduced graphene suspension with A solution as solvent, and sonicating at room temperature for 1-10 hours, adding the suspended gold suspension with the molar ratio of RGO and gold is 10:1-1:10, ultrasonicating turbid liquid for 0.1-10 hours, and centrifuging. USE - The method is useful for synthesizing RGO-gold complex nano materials. ADVANTAGE - The method: is simple and easy, and the prepared RGO-gold complex nano materials has broad application value and prospect.
