The rod-shaped, straw-like and flower-like products could be controllably obtained. The as-obtained products were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM） and Ultraviolet-visible （UV-Vis） absorption spectroscopy. The experimental results show that the morphology manipulation could be achieved by adding different amounts of NaH2PO4. XRD pattern indicates that the as-prepared sample is the pure tetragonal phase of β-FeOOH. UV-Vis absorption spectra of the products are affected by their morphologies, which shows that both the rod-shaped and straw-like β-FeOOH have outstanding absorption ability on the whole UV area （200-400 nm）, which will have vast application prospects in UV protection.展开更多
