Degradation of microcystin-LR by highly efficient AgBr/Ag3PO4/TiO2 heterojunction photocatalyst under simulated solar light irradiation

•AgBr/Ag3PO4/TiO2 consisting of less silver content possessed much higher photocatalytic activity than AgBr/Ag3PO4.•Reactive h+ and •OH played the major roles for MC-LR degradation by AgBr/Ag3PO4/TiO2.•AgBr/Ag3PO4/TiO2 photocatalyst was more stable than AgBr/Ag3PO4 in successive runs.•MC-LR was degr...
