Surface modification of Ag-CdO with polyaniline for the treatment of 3',3″,5',5″-tetrabromophenolsulfonphthalein (BPB) under UV-visible light irradiation.

The quality of natural waters could be deteriorated by organic pollutants which can impose a risk to the ecosystem as well as human health. These organic contaminants are often needed to be removed with adequate techniques. In this study, the photocatalysts of CdO nanoparticles (NPs), Ag-CdO nanocomposites (NCs), and Ag-CdO/polyaniline (PANI) NCs were successfully synthesized in order to investigate their degradation performance against 3',3″,5',5″-tetrabromophenolsulfonphthalein (bromophenol blue, BPB) dye.
