Zn(OH)F nanofibers with novel 3D-hierarchical structures have been synthesized from the reactions of Zn(NO3)2, hexamethylenetetramine (HMT) and NaF on a large scale by a facile solution-based method. Their structures and morphologies were characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The Zn(OH)F hierarchical architectures were assembled by many nanowires with a diameter of 20 nm. Their structures are dependent on the concentration of the reactants and the temperature of the reaction. The photocatalytic properties of these Zn(OH)F nanofibers were investigated by the decomposition of organic compounds and organic dyes under UV light irradiation and the results show that they have good photocatalytic activities.
