Abstract Photocatalytic selective oxidation of C(sp 3 )─H bonds into valuable carbonyl compounds offers a promising approach to advance green organic synthesis and contribute more sustainable chemical industry. However, significant challenges remain due the low efficiency photocatalysts, primarily caused by insufficient charge separation limited ability intermixed surface redox‐active sites precisely capture photoinduced carriers. Here, PEA 2 PbBr 4 /CeO (PPB/CeO ) p‐n heterojunction is designed fabricated. Experimental characterizations theoretical calculations reveal that strong internal electric field (IEF) formed at interface within heterojunction, which drives targeted accumulation holes on PPB electrons CeO . Importantly, displays superior oxygen affinity facilitating O reduction, while validates stronger adsorption activation capability toluene molecule promoting C─H bond dissociation. In this context, are directionally separated transported decoupled reduction in PPB/CeO , thereby significantly accelerating aerobic bonds. Toward photocatalytic model substrate toluene, optimized ‐5% composite exhibits conversion rate 10 050 µmol g −1 h nine times enhanced comparison with blank (1160 ).

Incorporating plasmonic nanostructures into photocatalysts significantly enhances catalytic efficiency due to effects. In this study, we successfully developed a heterojunction between organic semiconductor zinc porphyrin (Zn-TCPP) and colloidal gold (Au) nanoparticles connected via Au–O bonds. The formation of bonds Zn-TCPP Au facilitates charge transfer by reducing the Schottky barrier at interface. Finite-difference time-domain simulations, in situ XPS measurements, infrared thermal imaging confirm that strong localized surface plasmon resonance effect local electric field photothermal effect, promoting separation electron–hole pairs Zn-TCPP/Au sample improving reaction kinetics. optimal Zn-TCPP/Au-2% composite demonstrates an impressive H2 generation rate 1610 μmol·g–1·h–1, which is 2.7 8.6 times greater than TCPP samples, respectively. Additionally, shows high C–N coupling benzylamine imine, achieving yield 45.1 mmol·g–1 24 h. This study provides comprehensive understanding how activity photocatalysts.

Abstract The limited yield of H 2 production has posed a significant challenge in contemporary research. To address this issue, researchers have turned to the application surface plasmon resonance (SPR) materials photocatalytic generation. SPR, arising from collective electron oscillations, enhances light absorption and facilitates efficient separation transfer electron‐hole pairs semiconductor systems, thereby boosting efficiency. However, existing reviews predominantly focus on SPR noble metals, neglecting non‐noble metals semiconductors. In review, we begin by elucidating five different mechanisms, covering hot injection, electric field enhancement, scattering, plasmon‐induced resonant energy transfer, photo‐thermionic effect, which activity. Subsequently, comprehensive overview follows, detailing materials‐metals, semiconductors‐in production. Additionally, personal perspective is offered developing highly SPR‐based photocatalysis systems for solar‐to‐H conversion future. This review aims guide development next‐gen advancing solar‐to‐fuel conversion.
