Abstract: Zn doped Ba germanate nanorods have been prepared by the hydrothermal process and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and solid UV-vis diffuse reflectance spectroscopy. XRD analysis shows that the Zn doped Ba germanate nanorods consist of hexagonal Ba2Ge5O12 and rhombohedral ZnGeO₃ phases. The size and band gap of the Zn doped Ba germanate nanorods depend on the Zn doping mass percentage. The band gap of the 1wt.% Zn doped Ba germanate nanorods is 4.07 eV which is smaller than that of undoped and Zn doped Ba germanate nanorods with the Zn doping mass percentage of 3%, 5% and 10%. The role of the irradiation time and content of the nanorods in aqueous solution has been analyzed. The 1wt.% Zn doped Ba germanate nanorods show the highest photocatalytic activity under UV light irradiation. The photocatalytic activity has been greatly enhanced by the Zn doping.
