Modification of interface of Cd and Bi sulfides by surfactant for photocatalyticremoval of antibiotics

Due to unique electron transport properties, nanostructured catalysts with certain morphology, suchas nanotube, nanosheet and nanorods, have shown outstanding photocatalytic performance. The visible lightphotocatalytic ability of Bi۲S۳/CdS composites are investigated by photocatalytic removal of Levofloxacin. Theresults of photocatalysis indicate that removal efficiency of Levofloxacin over Bi۲S۳/CdS composite is higherthan those of pure CdS and Bi۲S۳. The enhanced photocatalytic performance of Bi۲S۳/CdS nanocompositecan be attributed to the improved visible light response and efficient charge separation and transfer. This workprovides new insights into building of the efficient and novel heterogeneous photocatalysts
