Abstract: Zn2GeO4 nanorods were prepared by a surfactant-assisted solution phase route. The as-prepared products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), inductively coupled plasma atomic emission spectrometer (ICP-AES), UV-vis diffuse reflection spectroscopy and photoluminescence (PL) spectroscopy. The possible formation mechanism of Zn2GeO4 nanorods was discussed. It was supposed that the CTA+ cations preferentially adsorb on the planes of Zn2GeO4 nanorods, leading to preferential growth along the c-axis to form the Zn2GeO4 rods with larger aspect ratio and higher surface area, which showed the improved photocatalytic activity for photoreduction of CO2. The photoluminescence (PL) property of Zn2GeO4 nanorods was investigated through the emission spectra.
