An ultrasonic‐assisted solvothermal route based on the hydrolysis of In 3+ was utilized to synthesize InOOH with a hierarchic three‐dimensional (3D) architecture, which was assembled by single‐crystalline nanowires with diameters of about 10 nm and lengths up to several hundred nanometers. X‐ray powder diffraction (XRD), field emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), and FTIR spectra were used to characterize the obtained products. Alkaline media and solvent play crucial roles in influencing the phase and the morphology of the products. A possible mechanism was proposed to explain the formation process of the InOOH 3D nanostructure. The optical properties of InOOH was also investigated by ultraviolet and visible (UV/Vis) spectroscopy, which indicated that InOOH is a wide band‐gap semiconductor.(© Wiley‐VCH Verlag GmbH & Co.
