To synthesize Ag-doped GO-Fe3O4 nanocomposites using a green method with plant extract for in situ reduction of Ag+, you can follow these general steps:

Synthesize graphene oxide (GO) using the modified Hummers method.

Disperse the synthesized GO in water and sonicate to obtain a homogeneous suspension.

Add an aqueous solution of AgNO3 dropwise to the GO suspension under continuous stirring.

Prepare a plant extract (e.g., Punica granatum peel extract, Eryngium planum leaf extract) and add it dropwise to the GO-AgNO3 mixture. The plant extract will act as a reducing agent for in situ reduction of Ag+ to Ag nanoparticles.

Adjust the pH of the mixture to around 9 using an aqueous solution of KOH.

Heat the reaction mixture under reflux conditions at 80°C for 24 hours.

Separate the resulting Ag-doped GO nanocomposite by centrifugation, wash it with water several times, and dry it in a vacuum oven at 50°C.

Disperse the Ag-doped GO in water and add iron(II) and iron(III) chlorides.

Carry out ultrasound-assisted co-precipitation of iron salts in the presence of Ag-doped GO to obtain the final Ag-doped GO-Fe3O4 nanocomposite.

Characterize the synthesized nanocomposite using techniques such as XRD, FTIR, SEM, EDX, TEM, and Raman spectroscopy to confirm the formation of the desired Ag-doped GO-Fe3O4 structure.

According to the above article:to synthesize Ag-doped GO-Fe3O4 nanocomposites using a green method with plant extract:

Synthesis of Graphene Oxide (GO):

GO can be synthesized from graphite powder using a modified Hummer's method, as mentioned in the search results.

Synthesis of Ag/RGO Nanocomposites:

Disperse 0.3 g of GO in 30 mL of water and sonicate for 15 minutes.

Add 15 mL of 0.1 M aqueous AgNO3 solution dropwise to the GO suspension and continue sonication for 1 hour.

Add 40 mL of 5.0 g/L aqueous Punica Granatum (pomegranate) peel extract dropwise to the mixture and adjust
