In this study, hierarchically-structured hollow CuO microspheres were utilized for potential solar light-assisted degradation of a model pollutant dye. Morphological analysis revealed that prepared hollow CuO microspheres (~9–16 µm) composed of small crystal strips pointed towards the center of the microsphere. Nitrogen adsorption–desorption experiments revealed that prepared hollow CuO microspheres have a specific surface area of ~12.184 m2/g. It was shown that prepared CuO microspheres can be used as an effective H2O2-assisted solar light-activated photocatalyst. In particular, prepared CuO microspheres significantly accelerate the degradation rate of aqueous Rhodamine B dye solution as compared to some other CuO structures reported to date. The recyclability study revealed that these CuO microspheres can be re-used several times without losing the photocatalytic activity.
