Photocatalytic reduction of 4-nitroaniline in aqueous solution using BiOCl/BiOBr/rGO ternary heterojunction under simulated UV-visible light irradiation.

BiOCl/BiOBr/rGO ternary heterojunctions were synthesized and characterized, and their photocatalytic activities were examined. Three different rGO mass ratios were incorporated into BiOClBiOBr; 1% rGO, 3% rGO, and 5% rGO, respectively. The successful incorporation of rGO into the composites was confirmed using powder X-ray diffraction (PXRD).
