The ZnO photocatalysts were prepared by hydrothermal and precipitation methods, and its phase and morphology were characterized by X-ray powder diffrac- tion （XRD） and scanning electron microscopy （SEM） to understand the material stru-ctural information reflected by XRD and SEM. Experiments were carried out using methylene blue as the pollutant object to evaluate and comparae with the photocataly- tic activity of ZnO catalysts to understand the influence of preparation methods for its crystal phase, morphology and catalytic properties.
