Interfacial engineering boosting the piezocatalytic performance of Z-scheme heterojunction for carbamazepine degradation: Mechanism, degradation pathway and DFT calculation

In this work, a Z-scheme Bi2S3-Bi2WO6 (BS-BWO) heterojunction with interfacial Bi-S bonds was constructed by in-situ growing Bi2S3 nanorods on Bi2WO6 nanosheets. The obtained BS-BWO heterojunction exhibited significantly enhanced piezocatalytic performance on carbamazepine (CBZ) degradation with an apparent rate constant of 0.087?min?1. Density functional theory (DFT) calculations together with experimental characterizations illustrated that the boosted piezocatalytic performance of BS-BWO could be ascribed to the Z-scheme charge transfer through the formed Bi-S bonds, which increased the charge transfer/separation efficiency and maintained the strong redox ability of photogenerated electrons/holes. Moreover, the increased piezoelectric potential of BS-BWO, as supported by COMSOL simulation, also contributed to the enhanced piezocatalytic performance. This study sheds light on the design and development of promising piezocatalysts for environmental remediation.
