One-pot hydrothermal synthesis of dual Z-scheme BiOBr/g-C3N4/Bi2WO6 and photocatalytic degradation of tetracycline under visible light

Bi2WO6/g-C3N4/BiOBr composite was simply synthesized by a one-pot hydrothermal process and exhibited excellent photocatalytic activities in Tetracycline degradation under visible light for 40 min with high efficiency of 90% due to the obviously increased charge separation. Photoelectrochemical measurements and radical (center dot OH, h(+) and O-2(center dot)) trapping experiments deduced the electron transfer mechanism. This work provided a facile synthesis method for bismuth based ternary heterostructures with potential applications in environmental remediation. (C) 2020 Elsevier B.V. All rights reserved.
