▎ 摘　　要

NOVELTY - Composite method of graphene oxide and metal nanoparticles comprises (i) placing graphene oxide in distilled water at room temperature and performing ultrasonic dispersion to obtain a graphene oxide dispersion liquid, (ii) taking 0.2-2.5 mmol/l metal salt solution and performing magnetic stirring at room temperature, after completely dissolved, heating to reflux, while adding 0.1-38.8 mmol/l of reducing agent, and stirring at 25-100 degrees C for 15-60 minutes to obtain a metal nanoparticle solution, (iii) adding 0.4-10 mmol/l stabilizer to the obtained metal nanoparticle solution at room temperature, and after ultrasonic self-assembly to obtain metal nanoparticles and (iv) stirring the obtained graphene oxide dispersion liquid and the metal nanoparticle solution and reacting at room temperature, centrifuging and washing to obtain a composite of graphene oxide and metal nanoparticles. USE - The composite method of graphene oxide and metal nanoparticles is useful in the fields of sensory detection, environmental protection and biomedicine.
