Flower‐like Ag/ZnO nanocomposites were successfully synthesised by a facile solvothermal method. The product was characterised by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet‐visible diffuse reflectance spectroscopy and photoluminescence (PL) spectroscopy. It was found that ZnO was in the wurtzite phase and the Ag metal particles were loaded on the surface of the ZnO nanosheet. Compared with pure ZnO, the Ag/ZnO nanocomposite displayed significantly visible‐light absorption, reduced PL emission intensity, and enhanced photocatalytic activity for the degradation of Rhodamine B, which could be attributed to an effective separation of the photo‐generated electron–hole pairs in the nanocomposite.
