摘要

•A new Z-scheme photocatalyst COF TzDa/Ag/AgBr is successfully fabricated.•Enhanced TC oxidation and Cr(VI) reduction are realized under visible light.•COF TzDa/Ag/AgBr simultaneously removes TC/Cr(VI) mixture with synergistic effect.•Mechanisms for TC degradation and Cr(VI) reduction are proposed.•COF TzDa/Ag/AgBr exhibits good stability in cyclic use on TC and Cr(VI) removal.
