One of the most sustainable and promising approaches for hydrogen peroxide (H2 O2 ) production in a low-cost environment-friendly way is photosynthesis, which, however, suffers from poor carrier utilization low H2 productivity. The addition proton donors such as isopropanol or ethanol can increase production, unfortunately, will inevitably elevate entire cost while wasting oxidizing power holes (h+ ). Herein, tetrahydroisoquinolines (THIQs) employed distinctive donor thermodynamically feasible selective semi-dehydrogenation reaction to highly valuable dihydroisoquinolines (DHIQs), meanwhile, couple with promote generation one photoredox under photocatalysis by dual-functional Zn3 In2 S6 photocatalyst. Surprisingly, suitably defective offers an excellent near-stoichiometric co-production performance DHIQs at unprecedentedly high rates 66.4 62.1 mmol h-1 g-1 visible light (λ ≥ 400 nm), respectively, which outperforms all previously available reports even though sacrificial agents were those reports. Additionally, photocatalytic redox mechanism demonstrates that be generated through multiple pathways, highlighting synergistic effect among ROS (·O2- 1 ), h+ donor, has been ignored previous studies.

Covalent organic frameworks (COFs) exhibit significant prospects in photocatalytic H2 evolution because of their periodic pore structure, large surface area, and outstanding chemical stability. Nevertheless, a bare COF always suffers from poor photogenerated charge separation efficiency. Hence, it is crucial to design highly effective COF-based heterojunction photocatalysts. In this work, we have successfully prepared an organic/inorganic hybrid TpPa-1-COF/ZnIn2S4 (ZIS) with well-matched S-scheme interfacial charge-transfer channels. The results demonstrate that COF/ZIS-20% has optimal rate, which can reach 853 μmol g–1 h–1 the absence any cocatalyst, 6.2 times TpPa-1-COF when exposed visible light. Moreover, apparent quantum efficiency (AQE) at 420 nm up 2.08%. Density functional theory (DFT) calculations demonstrated presence transfers ZnIn2S4 spontaneously formation electric field area COF/ZIS under ground-state condition. Furthermore, creation tuned built-in drives directional transfer, while electron high reduction, thus synergistically promoting evolution, been by experiments theoretical calculation results. This work provides advanced method for preparation high-efficiency photocatalysts based on matching band structures.
