摘要：

FeOOH nanorod array was synthesized utilizing a facile hydrothermal method. The photoreduction efficiency to Cr(VI) is 70% after 4 h illumination at pH < 3. The Mott-Schottky plots confirmed the n-type behavior and the donor density is calculated to be 6.91 x 10 16 cm(3). The best anodic photo-current is 90 nA/cm(2) under illumination of light with intensity of 0.02 W/cm(2). The onset potential of photo-current is -0.2 V (vs. Ag/AgCl (Sat. KCl)), which indicates the FeOOH nanorods array has an active interface. (C) 2018 Elsevier B.V. All rights reserved.
