Abstract: | Ag‐ZnO heterostructure was obtained through a simple method that is suitable for general laboratory production. The X‐ray diffraction (XRD), transmission electron microscopy (TEM) results showed that Ag‐ZnO heterostructure had excellent purity and crystalline properties. Meanwhile, the catalytic degradation results demonstrated that it had high photocatalytic activity to the degradation of rhodamine B (RhB). Besides, in order to explore the optimum catalytic activity of the sample, the influences of experimental parameters including additives, the amount of catalyst, the concentration and initial pH of RhB were studied in detail. |
