Facile construction of Z-scheme AgBr/BiO(HCOO)0.75I0.25 photocatalyst for visible-light-driven BPA degradation: Catalytic kinetics, selectivity and mechanism

•Z-scheme AgBr/BiO(HCOO)0.75I0.25 composites exhibited superior photocatalytic activity for BPA elimination.•Complicated water matrix only slightly affected the AgBr/BiO(HCOO)0.75I0.25/VL system.•O2−, 1O2 and photogenerated holes played primary roles in BPA degradation.•AgBr/BiO(HCOO)0.75I0.25/VL system exhibited a highly selective oxidation on aromatics with electron donating groups.
