Porous ZnO/BiOI microspheres composed of ultrathin nanosheets were successfully fabricated by an ethylene glycol-assisted solvothermal method, The morphology and size of the as-prepared samples were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), UV-Vis diffuse reflectance spectra (DRS), X-ray photoelectron spectroscopy (XPS) and N₂ adsorpion-desorption measurements. The photocatalytic degradation of RhB aqueous solution shows that the porous ZnO/BiOI microspheres have the highest photodegradation performance with visible light and acetaldehyde (CH₃CHO) gas degradation.This finding indicates that the heterojunction effect created between two different semiconductors is of importance in determining the dynamic properties of photogenerated charge transfer and the related photocatalytic properties.
