| Abstract: | One-step solvothermal synthesis of L-cysteine-coated Fe3O4 nanoparticles using FeCl3 and L-cysteine as precursors was completed.XRD,TEM,FT-IR,and TG-DTA techniques were employed to characterize the morphology and structure properties of the sample.The surface properties were studied by zeta potential measurement and potentiometric titration technique.The results show the formation of surface chemical bonds between L-cysteine and Fe3O4 nanoparticles;the particle size of Fe3O4/L-Cys is about 30nm;L-cysteine l... |
