The Zn2GeO4 nanorods photocatalysts with Ag doping and Ag decorating (Ag-modified Zn2GeO4) were synthesized by a mild solvothermal method. The as-prepared samples were characterized by Field Emission Scanning Electron Microscope (FE-SEM), transmission electron microscope (TEM), X-Ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectrum (EDS) measurements. The one-dimensional (1D) Ag-modified Zn2GeO4 The one-dimensional (1D) Ag-modified Zn2GeO4 nanorods exhibited excellent photo-degradation performance using RhB and phenol as model organic pollutants. The cycle degradation results revealed Ag-modified Zn2GeO4 nanorods had an excellent chemical stability. The active species trapping experiment suggested that the hydroxyl radicals and superoxide radical were the dominating active species, rather than holes.
