Abstract: ZnO is one of the most promising and widely studied materials due to its unique properties and remarkable performance in electronics, optics, and photonics etc. “Meanwhile, doping with selective element offers an effective method to enhance and control the electrical and optical properties of ZnO nanostructures, which is crucial for its practical applications”. Recently ZnO nanowires are used for a number of potential applications such as photocatalysis, solar cells, sensors, and generators. Among the applications of ZnO nanowires, photocatalysis is being increasingly used for environmental protection. In this paper we report a review of the current research on ZnO nanowires with special focus on photocatalysis. We have presented the semiconducting photocatalysts, discussed number of synthesis methods and their corresponding effectiveness in photocatalysis. We have also presented the characterization of ZnO nanowires from the literature. Finally, a wide range of uses of ZnO nanowires in various applications is highlighted there in.
