ZnO hollow spheres with nanometer to micrometer dimensions exhibit low density, large specific surface area, good surface permeability and excellent photoelectric properties, so they have attracted a great deal of attentions. The preparation methods and application fields of ZnO hollow microspheres are reviewed. Firstly, the progress of the preparation methods of ZnO hollow microspheres, such as hard-template method, soft-template method, self-template method and template-free method, is summarized. Secondly, the application research and development of ZnO hollow microspheres in photocatalysis, solar cells, gas sensors, biological medicine and other areas are intro- duced. Finally, perspectives on the future research and development of ZnO hollow microspheres are discussed.
