Hydrangea‐like ZnO nanospheres were fabricated on Al substrates via a facile hydrothermal method with only one step. Scanning electron microscopy, energy‐dispersive spectroscopy, X‐ray diffraction, X‐ray photoelectron spectroscopy, and photoluminescence were used to investigate their morphology, component, structure, and optical properties. The hierarchical nanospheres are fabricated by 2D nanosheets with the shape of 3D sphere. By adjusting the reaction time, the formation process was monitored. The photocatalytic activity of ZnO nanospheres was also investigated for their dye degradation, and they exhibit good photocatalytic ability to congo red, with the degradation rate of 98.4%. Besides, they have universal catalysis effect on methyl orange.
