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.

ZnIn2S4 (ZIS) is widely used in the field of photocatalytic hydrogen production due to its unique photoelectric properties. Nonetheless, performance ZIS usually faces problems poor conductivity and rapid recombination charge carriers. Heteroatom doping often regarded as one effective strategies for improving catalytic activity photocatalysts. Herein, phosphorus (P)-doped was prepared by hydrothermal method, whose energy band structure were fully studied. The gap P-doped about 2.51 eV, which slightly smaller than that pure ZIS. Moreover, upward shift band, reduction ability enhanced, also exhibits stronger optimized a rate 1566.6 μmol g-1 h-1, 3.8 times pristine (411.1 h-1). This work provides broad platform design synthesis phosphorus-doped sulfide-based photocatalysts evolution.
