Abstract Despite the significant milestones in half‐reduction process of photocatalysis, challenges remain fully utilizing electron–hole pairs simultaneous redox reactions. Herein, a Z‐scheme ZnIn 2 S 4 /W 18 O 49 (ZW) hybrid with complementary band edge potential is situ constructed. The resultant fuzzy 1D‐assembled sea‐urchin photocatalyst demonstrates an optimal H and benzaldehyde yield 122 106 µmol h −1 under λ > 420 nm light irradiation. This sacrificial‐agent‐free system entails solar‐to‐hydrogen (STH) apparent quantum efficiency (AQE) values 0.466% 2.48% (420 nm), respectively, surpassing most recently reported photocatalytic systems without aid noble metal cocatalysts. outstanding performance mainly attributed to synergistic formation intimate heterojunction induction localized surface plasmon resonances. Comprehensive characterization studies prove direct injection energetic hot electrons promote number long‐lived active electrons. Besides, electron paramagnetic resonance scavenger tests clarify complicated mechanistic puzzle dual‐redox reaction, where formed dominantly via O─H activation followed by C─H cleavage benzyl alcohol over ZW hybrid. Lastly, universal use composites testified various systems. study offers novel outlook for designing dual‐functioning heterojunctions toward feasible photoredox application.

ChemSusChem, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 19, 2024

Near-infrared (NIR) light, accounting for approximately 50 % of solar cannot directly excite photocatalytic reactions due to its lower energy, which severely restricts the energy conversion efficiency and hinders application photocatalysis. To overcome this dilemma, some viable strategies have been proposed harness NIR light enhancing performance based on material structure, composition, function designs, obvious progresses witnessed. In review, basic principles representative advances in photocatalyst heterojunction designs (including p-n junctions, S-scheme, Z-scheme, type-ІІ heterojunctions), composition (such as preparing rare earth element doped upconversion photocatalysts, hybrids triplet-triplet annihilation composites), photothermal-photocatalytic bifunction utilization are exclusively scrutinized. Meanwhile, applications above-mentioned responsive composites environmental fields summarized. Importantly, challenges outlooks field harnessing efficient photocatalysis proposed, may provide theoretical experimental guidance those working other related fields.
