摘要：

Hydrogen peroxide (H₂O₂) is a valuable chemical for various industries, while the current H₂O₂ production still suffers from multistep reaction processes, large consumption of organic solvents and waste-intensive. The photooxidation of water coupled with photo-reduction of oxygen is the cheapest and cleanest pathway to produce H₂O₂. Herein, we demonstrated that ZIF-8/C₃N₄ composite, as an efficient dual-channel photocatalyst, can produce H₂O₂ under visible light (λ ≥ 420 nm) with high efficiency (2641 μmol h⁻¹ g⁻¹ ) at normal pressure and without any sacrificial agent. The apparent quantum efficiency (AQE) can be calculated to be 19.57 % at the wavelength of 420 nm. Notably, the concentration of H₂O₂ generated is up to 0.71 wt.% at 420 nm (10 mg catalyst with 15 mL O₂ saturated H₂O), which is very close to the concentration of industrial production (1 wt.%) by anthraquinone method. Our work may provide a ultra-green pathway for the photo-production of H₂O₂ to meet industrial requirement.
