“…It has been proven that the in-plane biaxial strain can change the out-of-plane dipole moment of g-ZnO and achieve the band structure modulation of g-ZnO-based vdWHs as novel photocatalysts . Electric field engineering has been proved to be a nondestructive and reversible method to continuously tune the electronic properties of vdWHs. − It has been reported that external electric field might lead to occupied nearly free-electron (NFE) states in some materials, like GaSe/GeS heterostructures . Usually, the NFE states possess high energies and exist far above the Fermi level ( E f ), and these unoccupied NFE states are unsuitable for charge transport. , Materials with the occupied NFE states can provide effective electron transport channels in nanoelectronic devices, and can be applied in gas sensors and high-temperature superconductors. , …”

Using hybrid density functional theory calculations, we systematically study the biaxial strain and electric field modulated electronic properties of g-ZnO/SnS 2 , g-ZnO/SnSe 2 , and g-ZnO/SnSSe S-scheme van der Waals heterostructures (vdWHs). g-ZnO/SnS 2 and g-ZnO/SnSSe are found to be promising photocatalysts for water splitting with high solar-tohydrogen efficiencies, even under acidic, alkaline, and high-stress conditions. The strain effect on the bandgaps of g-ZnO/SnXY is explained in detail according to the correlation between geometry structure and orbital hybridization of SnXY, which could help understand the strain-induced band structure evolutions in other SnXY (X, Y = S, Se)-based vdWHs. It is surprising that under an external electric field, g-ZnO/SnS 2 , g-ZnO/SnSe 2 , and g-ZnO/SnSSe can offer the occupied nearly free-electron (NFE) states. In many materials, NFE states are usually unoccupied and is not conducive to the charge transport. The NFE state in g-ZnO/SnSe 2 is the most sensitive to the electric field and might be promising electron transport channel in nanoelectronic devices. g-ZnO/SnSe 2 might also have application potential in gas sensors and high-temperature superconductors.

The critical challenges of the energy crisis and environmental degradation promote innovative approaches for energy conversion. Semiconductor‐based photocatalytic technology, which transforms solar energy into chemical energy, emerges as a promising solution. However, the practical application of this technology faces several challenges, such as the rapid recombination of photogenerated electrons and holes, significantly limiting photocatalytic efficiency. In this review, we provide a detailed discussion, an insightful perspective, and a critical evaluation of recent advances, challenges, and opportunities in the field of photocatalysis using polar materials. We present a comprehensive examination of the photocatalytic mechanisms, activity, and diverse applications of photocatalysts based on polar materials. We also briefly discuss the engineering design of polar photocatalysis in experiments and its scalability in the industry. This review outlines future trends and potential breakthroughs in the photocatalytic field using polar materials, projecting their transformative impact on environmental chemistry and energy engineering.
