Photo-Decomposition of Antibiotic Pollutant Over Bismuth Subcarbonate Under Simulated Solar Light

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#
