文摘
- •
Monodispersed Fe3O4 nanoclusters were synthesized in a one-pot 5-sulfosalicylic acid assisted solvothermal route.
- •
The size of the clusters are tunable by varying the amounts of 5-sulfosalicylic acid and the volume ratio of DEG/EG.
- •
The nanoclusters exhibited superparamagnetic properties with high saturation magnetization value.
- •
The 5-sulfosalicylic acid grafted Fe3O4 nanoclusters can be dispersed in water.
