Oxygen-rich bismuth oxybromide nanosheets coupled with AgO as Z-scheme nano-heterostructured plasmonic photocatalyst: Solar light-activated photodegradation of dye pollutants.

In this research to enhance the photocatalytic activity of BiOBr, precipitation fabrication of the Z-scheme heterojunction with Ag-AgO has been investigated. The characterizations were carried out by XRD, FESEM, TEM, EDX, BET-BJH, DRS and pH analyzes. The Ag-AgO/BiOBr Z-scheme heterojunction nanophotocatalyst with weighted ratio of 3:1 exhibited the wide absorption in the visible light region and displayed the high photocatalytic activity for the photodegradation of acid orange 7 (96.
