摘      要：In this study, Ag2ZnGeO4 flower-like hierarchical nanostructure was prepared using a simple and mild method. The as-prepared samples were characterized with X-ray diffraction, scanning electron micros- copy, transmission electron microscopy, energy dispersive X-ray spectroscopy, UV-vis diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, and N2 adsorption and desorption isotherms. Mean- while, the photocatalytic activity of the as-prepared samples was explored using Rhodamine B as a model pollutant, The results indicated that the Ag2ZnGeO4 hierarchical nanostructures obtained consisted of nanoplates and nanurods, and adopted spherical flower-like morphology. Moreover, the as-prepared Ag2ZnGeO4 hierarchical nanostructure was an efficient and stable visible-light photocatalyst for the deg- radation of organic dyes in water. After visible light irradiation for 105 rain, the degradation of Rhodamine B was up to 92%. Moreover, the photocatalytic activity of Ag2ZnGeO4 remained unchanged after three successive cycles,
