Controlled Fabrication and Characterization of α-FeOOH Nanorods

α-FeOOH nanorods was successfully synthesized by hydrothermal method. The key factors influencing the hydrothermal preparation of this material were reported, and the effects of iron source concentration, alkali reaction time, hydrothermal temperature and hydrothermal time on the morphology and structure of α-FeOOH nanorods were discussed in depth. The synthesized nanomaterials were characterized by XRD, TEM and SEM, and the results showed that each experimental parameter had a great influence on the morphology and structure. The experiment should be carried out with the participation of alkali, and the concentration of iron salt was the key to the formation of nanomaterials, besides, the calcination time and the calcination temperature played important roles in the growth of rod length and diameter. The morphology of the prepared nanorods was controllable, and the nanorods might have potential application value in the fields of drug formulation, adsorption, electrochemistry, etc.Graphical AbstractA novel α-FeOOH nanorods was successfully synthesized by hydrothermal method.
