x Cl1-x (0xCl 1-x . The UV-visible diffuse reflectance and photoluminescence (PL) spectroscopies revealed the indirect band gap of ∼2.82 eV for the bismuth oxybromochloride nanoflakes. Visible light-assisted photocatalytic studies showed that the degradation efficiency of the as-prepared BiOBrx Cl1-x for (100 mL of 10 mg L-1) Rhodamine B (RhB), Natural Red 4 (N-Red) dye solutions was 98.14% and for the colorless organic pentachlorophenol (PCP) solution was 91.09% over 150 min. The possible mechanisms involved in the visible light photodegradation of the pollutants by BiOBrx Cl1-x photocatalyst were also discussed - Keywords:
