The synthesis of flower-like bismuth subcarbonate (Bi2O2CO3) as nanophotocatalyst by sono-hydrothermal method and its application is reported here. The prepared Bi2O2CO3 flower-like is characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The XRD result was confirmed the correct synthesis of this sample. Moreover, the photocatalytic activity of bismuth subcarbonate was evaluated during photo-decomposition experiments of tetracycline hydrochloride (TCH) under simulated sunlight irradiation. The results obtained vs. irradiation time were 46.3, 64.2, 71.0 and 73.6% after 30, 60, 120 and 180 min illumination, respectively. These results imply the successful performance of bismuth subcarbonate in the elimination of environmental pollutions, especially aquatic systems.
