Molecular‐Level Control of the Intersheet Distance and Electronic Coupling between 2D Semiconducting and Metallic Nanosheets: Establishing Design Rules for High‐Performance Hybrid Photocatalysts

摘要: Hybridization with conductive nanospecies has attracted intense research interest as a general effective means to improve the photocatalytic functionalities of nanostructured materials. To establish universal design rules for high-performance hybrid photocatalysts, correlations between versatile roles species and interfacial interaction hybridized are systematically investigated through fine-control intersheet distance photocatalytically active TiO2 metallic reduced graphene oxide (rGO)/RuO2 nanosheets. Molecular-level tailoring electronic coupling 2D nanosheets can be successfully achieved by restacking colloidal nanosheet mixture variable-sized organic intercalants. While shortest restacked rGO leads highest visible-light-driven activity, best UV-vis photocatalyst performance occurs moderate spacing. These results highlight greater sensitivity photoinduced excitation than that charge transfer. The function transport pathway cocatalyst within ≈1.7 nm from semiconducting nanosheet, efficient stabilizer ≈1.8 nm. present study underscores intercalative intercalants enables molecular-level control inorganic/graphene nanosheets, which provides rational strategy photocatalysts.
