Abstract An Ag 2 O–ZnO nanohybrid is synthesized for the first time through a facile, basic coprecipitation‐assisted hydrothermal strategy. This novel method endows the Ag 2 O–ZnO nanohybrid (Ag 2 O/ZnO=0.3:0.7) with small particle size and strong electronic synergistic effects owing to the uniform distribution of the constituents. The as‐synthesized nanohybrid shows excellent photocatalytic properties for degradation of rhodamine B, even under visible light irradiation. This effect is much better than pure or physical mixtures of Ag 2 O and ZnO, as well as the traditional homogenous Fenton catalyst (Fe 3+ /H 2 O 2 ).
