摘要：

Pearl necklace-like ZnO-ZnWO4 heterojunctions composites have been designed and synthesized. The photocatalytic activity of the ZnO-ZnWO4 heterojunctions depended on the calcination temperature and ZnO-ZnWO4 molar ratio. The ZnO-ZnWO4 composites showed higher degradation efficiency than that of ZnO or ZnWO4 individually. The photocatalytic reaction was enhanced due to the heterojunctions construction, which improved charge separation of the photogenerated electron-hole pairs.
