The fluffy porous structure ZnO nanocrystals have been successfully synthesized using citric acid assisted sol-gel method. The ZnO nanocrystals were systematically characterized by XRD, SEM, UVS, and TGA/DSC. Finally, the ZnO nanocrystals were investigated in the photodegradation experiment. The results indicated that the highly photocatalytic activity was exhibited using ZnO nanocrystals as photocatalyst.
