Abstract In this paper, we have reported a facile strategy to fabricate a core/shell/shell structured CuO@ZnO@CoFe 2 O 4 nanocomposite with enhanced UV‐light‐driven photocatalytic activity that is capable of fast magnetic separation. Photocatalytic examination of the as‐prepared photocatalyst was carried out using methylene blue (MB) solution under UV irradiation. A hypothesized reaction mechanism was presented, showing the introduction of CuO into ZnO@CoFe 2 O 4 nanocomposite facilitates charge separation by trapping photo‐generated electrons, therefore improves the photocatalytic properties. The resultant multifunctional nanocomposite was thoroughly characterized by a series of techniques including XRD, EDX, FTIR, SEM, TEM and VSM.
