Abstract The development of catalysts that are optically transparent, electrically charge‐transferable, and capable protecting underlying photoactive semiconductors is crucial for efficient photoelectrochemical (PEC) hydrogen production. However, meeting all these requirements simultaneously poses significant challenges. In this study, the fabrication a wafer‐scale transparent bilayer MoS 2 /WS catalyst presented with staggered heterojunction, optimized photon absorption, extraction photogenerated charge carriers, surface passivation p ‐Si photocathode. WS monolayers grown via metal‐organic chemical vapor deposition, followed by sequential transfer stacking onto resulting type‐II heterojunction film establishes strong built‐in electric field rapid carrier transport effectively protects Si from oxidation corrosion. fabricated /p‐Si photocathode demonstrates outstanding PEC performance, achieving high photocurrent density −25 mA cm −2 at 0 V versus reversible electrode, along enhanced stability compared to monolayer /p‐Si. This work provides promising strategies developing active, protective practical energy conversion systems.

Photoelectrochemical (PEC) synthesis offers a sustainable route for fine chemicals production, yet comprehending and modulating the reaction processes at atomic level remains challenge. Herein, we develop single-atom Ir decorated Ti-doped α-Fe2O3 photoanode selective PEC of adipic acid from cyclohexanone using water as oxygen source. The system achieves 6.0 μmol cm-2 h-1 production with ~60% Faradaic efficiency ~88% selectivity. promotes photogenerated carrier separation transfer, while regulating electronic structure to optimize its adsorption strength OH- cyclohexanone. Mechanistic studies reveal non-free-radical pathway level, driven by holes through an adsorbed hydroxyl transfer. Notably, integrating amorphous silicon-based photocathode leads bias-free device that enables stable over 80 hours, underscoring potential light-driven synthesis.
