“…Polarization electric field is commonly employed as a descriptor to characterize the electronic and chemical structure variations of catalysts. − Given the alternating stacking [S–Zn]–[S–In–S]–[In–S] unit in layered hexagonal ZIS, the asymmetrical charge distribution exists along the [001] direction (Figure S3). , This intrinsic noncentrosymmetric property may affect its interaction orientation with surface modifier and further induce distinct changes in the dipole moment. Therefore, density functional theory (DFT) calculations were first conducted to shed light on the adsorption behaviors of the Rh complex on the ZIS surface.…”

Photocatalytic conversion of cofactor NAD + to NADH could inspire versatile and valuable biosynthesis using renewable solar energy. However, most previous photocatalytic systems necessitate leveraging sacrificial electron donors due to the complexity of kinetics coupling, resulting in a real "sacrifice". Herein, we report an integrated path for photocatalytic NADH regeneration fueled by selective alcohol oxidation over polarized ZnIn 2 S 4 (ZIS). Notably, the conventional electron mediator Rh complex was found to be facilely coordinated onto the ZIS surface, rendering the modulation of the internal and interfacial dipole field. The pronounced charge redistribution establishes favorable kinetics for seamlessly integrating photocatalysis and enzymatic catalysis. The maximum cofactor regeneration efficiency could reach 13.5 mmol g −1 h −1 with AQY up to 26.8% under 420 nm. Concurrently, the induced interfacial polarization promotes benzyl alcohol adsorption and subsequent C−H and O−H bond cleavage, thereby boosting the oxidation half-reaction rate and selectivity. This study bridges the gap in photoenzymatic CO 2 conversion by combining selective oxidative upgrading with efficient cofactor recycling.

Metal sulfide‐based homojunction photocatalysts are extensively explored with improved photocatalytic performance. However, the construction of metal sulfide‐based S‐scheme homojunction remains a challenge. Herein, the fabrication of 2D CdIn2S4 nanosheets coated 3D CdIn2S4 octahedra (referred to as 2D/3D n‐CIS/o‐CIS) S‐scheme homojunction photocatalyst is reported by simply adjustment of polyvinyl pyrrolidone amount during the solvothermal synthesis. The formation of S‐scheme homojunction within n‐CIS/o‐CIS is systematically investigated via a series of characterizations, which can generate an internal electric field to facilitate the separation and migration of photogenerated electron‐hole pairs. The 2D/3D n‐CIS/o‐CIS composite exhibits significantly improved photocatalytic activity and stability in the selective oxidation of phenylcarbinol (PhCH2OH) to benzaldehyde (PhCHO) when compared to pure n‐CIS and o‐CIS samples under visible light irradiation. It is hoped that this work can contribute novel insights into the development of metal sulfides S‐scheme homojunction photocatalysts for solar energy conversion.
