摘要:Achieving structural optimization and component modulation in ZnIn2S4-based photocatalysts while performing photocatalytic hydrogen evolution and degradation performance is a great challenge. In this work, a BN/MXene/ZnIn2S4 S-scheme photocatalytic heterojunction was obtained by growing the etched BN/MXene on the ZnIn2S4 nanosheets directly. Among them, introducing a special electron trapping effect of MXene successfully avoids the photocatalytic inferiority caused by the broader band gap of BN with weak conductivity and poor photocatalytic response activity. Therefore, a stable photocatalytic heterojunction can be constructed by adding MXene. The S-scheme heterojunction was identified by UPS, EPR, VB-XPS and Mott-Schottky measurements. The bifunctional composite heterojunction photocatalyst exhibited excellent hydrogen production performance (~1455 μmol·g-1·h-1) and 4-chlorophenol (4-CP) degradation ability (90%) with good stability compared to the that of pure BN/MXene and the ZnIn2S4 samples. In particular, the formation of a built-in electric field at the interface between BN/MXene and ZnIn2S4 n-type semiconductors provides directional acceleration of effective separation of the photogenerated charges and preserves excellent redox capability of the semiconductors. With the excellent hydrogen production performance and 4-CP degradation efficiency of the constructed bifunctional BN/MXene/ZnIn2S4 heterojunction, this work provides a feasible strategy for constructing an S-scheme heterojunction for energy and environmental remediation.
