摘要: 共价有机框架材料(COFs)因其结构可精确调控且具有高比表面积，被认为是极具前景的过氧化氢(H₂O₂)光催化合成材料。然而，pH值对COFs在光催化合成H₂O₂过程中稳定性的关键影响尚不明确。本研究通过简单质子化策略显著提升了亚胺连接型COF的光催化H₂O₂合成性能。值得注意的是，质子化COF在弱酸性条件(pH ≥ 3)下表现出优异的稳定性，但在强酸性条件(pH < 3)下会发生不可逆水解。质子化过程发生在亚胺单元的氮原子上，具有双重功能：抑制超快电荷复合(由飞秒瞬态吸收光谱证实)以及直接为H₂O₂生成提供质子源。此外，在光催化体系中引入氟离子(F⁻)可进一步提高H₂O₂产率，F⁻的强电负性促进了电子从COF向F⁻转移，从而实现光生载流子的空间分离。机理研究证实H₂O₂通过双电子氧还原反应路径生成。这些发现阐明了质子化COFs的pH依赖性稳定性与活性，为载流子转移动力学提供了思路，并为开发高效稳定的COF基光催化剂用于太阳能驱动H₂O₂合成确立了设计原则。

Abstract: Covalent organic frameworks (COFs), recognized for their precisely tunable microstructures and high surface area, are promising photocatalysts for H₂O₂ production. However, the critical influence of pH on the stability of COF during the photocatalytic H₂O₂ production remains poorly understood. In this work, the photocatalytic H₂O₂ production performance of an imine-linked COF is significantly enhanced through a simple protonation strategy. Crucially, the protonated COF exhibits excellent stability under weakly acidic conditions (pH ≥ 3), but undergoes irreversible hydrolyzed under strongly acidic conditions (pH < 3). The protonation occurs specifically at the nitrogen atoms of imine units and serves a dual function: it suppresses ultrafast charge recombination (as revealed by femtosecond transient absorption spectroscopy) and directly provides a proton source for H₂O₂ generation. Moreover, fluoride ions (F⁻) are introduced into the photocatalytic system to further improve the photocatalytic H₂O₂ production rate. The strong electronegativity of F⁻ facilitates electron transfer from COF to F⁻, thus realizing the spatial separation of photogenerated carriers. Mechanistic studies confirm that H₂O₂ production follows a two-electron oxygen reduction reaction pathway. These findings elucidate the pH-dependent stability and activity of protonated COFs, provide fundamental insights into charge carrier dynamics, and establishe design principles to develop highly efficient and stable COF-based photocatalysts for solar-driven H₂O₂ generation.
