Herein, Bi 2 WO 6 @Black‐TiO 2 hierarchical heterogeneous network architectures are prepared by coupling Bi 2 WO 6 nanosheets with a three‐dimensional B(black)‐TiO 2 network structure via a sequence simple hydrothermal/solvothermal strategy for application in water pollution remediation. The optimized Bi 2 WO 6 @B‐TiO 2 ‐2.0 photoelectrode exhibits excellent PEC degradation efficiency for sulfamethoxazole and various organic pollutants, including reactive brilliant blue KN‐R, rhodamine B, and bisphenol A. And the Bi 2 WO 6 @B‐TiO 2 ‐2.0 photoelectrode also demonstrated well catalytic stability by long‐term stability and recycling experiments, which can be attributed to its unique nanonetwork structure bringing an abundance of active sites. Furthermore, a S‐Scheme carriers transfer mechanism with solid ability to induce long lifetime electron/hole with strong redox, was identified via in situ x‐ray photoelectron spectroscopy and time‐resolved photoluminescence, resulting in the efficient production of active species (·OH and·O 2 − ) to achieve superior PEC degradation efficiency. The work reveals Bi 2 WO 6 @B‐TiO 2 ‐2.0 as promising catalysts for water remediation but also unlocks that S‐Scheme heterojunctions facilitate carrier transport and utilization, guiding the designing of heterojunctions for other optoelectronic applications. 10.1002/clem.70021 http://creativecommons.org/licenses/by/4.0/ |
