Atomically precise metal nanoclusters (NCs) emerge as a novel class of photosensitizers, distinguished by their discrete energy band structures and abundance catalytically active sites; however, broader adoption in heterogeneous photocatalysis remains hindered the challenges ultrashort carrier lifetimes, limited stability, complexity charge transport regulation. In this work, we conceptually design NCs photosensitized graphene (GR)-encapsulated transition chalcogenide (TMC) (GR/metal NCs/TMCs) heterostructure via cascade electrostatic self-assembly strategy. multilayer ternary heterostructure, are integrated between TMCs GR nanosheets, which act photosensitizers for enhancing light absorption meanwhile increase density composite photosystem. The favorable interfacial along with advantageous electron-withdrawing capability simultaneously boosts separation over NCs. Benefiting from such peculiar characteristics, self-assembled GR/metal NCs/TMCs demonstrates remarkably boosted stable photoactivities toward selective photoredox organic transformation, including photocatalytic anaerobic reduction aromatic nitro compounds to amino derivatives oxidation alcohols aldehydes under visible light. Furthermore, mechanisms underlying processes elucidated clarity. Our work affords quintessential paradigm customizing atomically engineered photosystems aimed at converting solar into chemical energy.

Abstract Constructing heterojunction photocatalysts with optimized architecture and components is an effective strategy for enhancing CO 2 photoreduction by promoting photogenerated carrier separation, visible light absorption, adsorption. Herein, defect‐rich (Ni P@Ce‐BDC‐CeO HOOs) S‐scheme hollowed‐out octahedral are prepared decomposing Ce‐BDC octahedrons embedded Ni P nanoparticles subsequent lactic acid etching photoreduction. The multistage pores (micropores, mesopores, macropores) oxygen vacancy defects simultaneously produced during the preparation process. boosts quick transfer separation of photoinduced charges. formed multi‐stage pore structure favorable adsorption diffusion molecules gaseous products. As expected, photocatalyst exhibits excellent performance, producing a yield 61.6 µmol h −1 g , which four times higher than that original octahedrons. X‐ray photoelectron spectroscopy, scanning Kelvin probe, electron spin resonance spectroscopy characterizations confirm S‐schematic charge‐transfer route. key intermediate species process detected in situ Fourier transform infrared to support proposed mechanism This work presents synthetic catalysts potential prospects photocatalytic applications.
