Constructing van der Waals (vdW) heterostructures is the most commonly used method for separating photogenerated carriers, which can effectively improve photocatalytic water-splitting efficiency. Although many vdW heterostructure photocatalysts have been proposed, there still a lack of effective strategies to regulate reaction ability. In this work, we propose ${\mathrm{Sc}}_{2}{\mathrm{CO}}_{2}/{\mathrm{Pt}\mathrm{S}}_{2}$ that achieve switch with different polarization directions (P \ensuremath{\uparrow} and P \ensuremath{\downarrow}). Both \ensuremath{\downarrow} are semiconductors type-II band-edge distribution. Remarkably, through analysis band arrangement built-in electric field, found two completely carrier-migration mechanisms inside heterostructures. The be as direct Z-scheme photocatalyst, showing great application prospect water splitting. contrast, cannot undergo reactions affected by direction field. Therefore, based on heterostructure, ``on'' ``off'' photocatalysis successfully achieved in single material. Additionally, Gibbs free-energy calculation, high light absorption, strain tunable gap indicate promising candidate applications.

Exploring and designing an efficient S-scheme heterojunction photocatalyst for water splitting are crucial. Herein, we report the interfacial electronics, photoexcited carrier dynamics, photocatalytic performance of MoSi2N4/SnS2 van der Waals under modulation electric field biaxial strain. Our results show that has a direct band gap 0.41 eV obeys charge transfer mechanism. Further calculations dynamics demonstrate recombination time is 7.22 ps, which shorter than electron (hole) 39.5 ps (566 ps). Moreover, effect positive tensile strain, exhibits excellent visible-light absorption, satisfactory band-edge potentials, tunable transfer, spontaneous hydrogen evolution reaction activity. The calculated STH efficiency indicates strain 2% most effective means improving heterojunction.
