In this study, Bi2MoO6 nanosheets were fabricated by a facile hydrothermal method. The physicochemical properties and morphology of the as-prepared Bi2MoO6 nanosheets were characterized by XRD, XPS, DRS and FESEM technologies. Photocatalytic results indicated that the Vis/Bi2MoO6/PS system was much more efficient than Vis/Bi2MoO6 and Vis/PS individual binary systems in TC-HCl degradation. The effects of catalyst dosage (0-0.8 g/L), initial TC-HCl concentration (20-120 ppm), PS concentration (0-10 g/L), initial solution pH (2-10) and coexisting anions (Cl-, NO3-, SO42-) on the TC-HCl removal efficiency were studied. Recycle experiments proved that the catalyst exhibited excellent stability and reusability in degrading TC-HCl molecules through activation of PS. In addition, trapping experiments revealed that SO4 center dot- and h(+) were the dominant radicals during degradation process. Finally, the possible mechanism for degrading TC-HCl in the Vis/Bi2MoO6/PS system was proposed.
