Uniform 3D rod‐like α‐Fe 2 O 3 nanostructures are prepared by a simple ultrasonic‐assisted hydrolysis precipitation method. The obtained α‐Fe 2 O 3 samples are characterized by X‐ray diffraction (XRD), Fourier transform infrared spectrum (FTIR), scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS), and electrochemical workstation. These rod‐like α‐Fe 2 O 3 nanostructures, with a mean diameter of about 38 nm, their ratios of length to diameter are about 5–8. The interfacial electron transfer properties of rod‐like α‐Fe 2 O 3 nanostructures are verified. The current synthetic strategy provides a convenient, low‐cost, and nontoxic route to prepare 3D architectures of other semiconductors, and it is important for exploring oxide‐based nanostructures.
