Synthesis of novel AgI/BiOI nanocomposites and their high-efficiency visible-light-driven photocatalytic degradation performance for norfloxacin

AgI/BiOI composites are prepared with BiOI nanosheets as the substrate by an in situ ion-exchange process. The AgI/BiOI-1.2 with a Ag/Bi molar ratio of 1.2 demonstrates a Bi 5 O 7 I composition and a high photocatalytic performance for NOR degradation.
