Designed 2D/2D F-doped TiO@ZnInS heterojunction for efficient photo-utilization hydrogen generation.

Comprehending the catalytic reaction implementation for heterostructure photocatalysts is crucial by scrutinizing the spatial separation and transfer process of photoexcited charges at nanoscale junctions. Herein, we fabricated the F-doped TiO/ZnInS-based S-scheme heterostructure using a direct liquid-assembly method. The optimum hydrogen evolution rate (HER) of ∼ 1.

Boosted photocatalytic hydrogen evolution of S-scheme N-doped CeO@ZnInS heterostructure photocatalyst.

The advancement of highly effective heterojunction photocatalysts with improved charge separation and transfer has become a crucial scientific perspective for utilizing solar energy. In this study, we developed the S-scheme heterostructure by depositing N-doped CeO (NC) nanoparticles onto two-dimensional ZnInS (ZIS) nanosheets via hydrolysis strategy for significantly enhanced photocatalytic hydrogen evolution reaction. The optimal H generation rate of ∼ 798 μmol g h was achieved for NC-3@ZIS under solar light irradiation, which is about 18 and 2 times higher than those of pristine CeO (∼44 μmol g h) and ZIS (∼358 μmol g h), respectively.
