摘要:

面对日益严峻的能源危机与环境挑战, 太阳能驱动的光催化转化已成为实现可持续发展的关键技术路径之一. 共价有机框架材料凭借其结构可调性、高结晶度及有序孔道等优势, 为突破传统无机半导体材料在分子水平上难以精准调控的瓶颈提供了全新平台. 然而, 当前基于COF粉末的光催化体系仍受制于光生载流子复合率高、光响应范围窄等局限, 同时, 在宏观应用中面临催化剂回收困难、易团聚失活、难以集成于连续流反应系统等工程难题, 严重阻碍了其从基础研究向实际应用的转化. 因此, 开发兼具高效电荷分离能力与宏观可操作性的新型COF光催化体系, 具有重要的科学意义和应用价值.

本文系统阐述了一种从分子到宏观尺度的跨尺度工程策略, 旨在通过协同纳米尺度的异质结设计与宏观尺度的膜结构工程, 以破解上述瓶颈. 首先, 从分子工程视角出发, 系统梳理了COF基异质结的设计思路与优势, 总结了将COF与无机半导体、金属及量子点等材料复合的多样化策略, 重点分析了S型异质结在促进空间电荷分离、保持强氧化还原能力方面的独特机制, 并归纳了决定其光催化性能提升的构效关系, 揭示了界面相互作用对载流子迁移路径的关键影响. 其次, 从宏观结构工程层面, 详细评述了COF膜的制备技术(如界面聚合法、原位生长法、层层堆叠法), 阐明了通过调控膜厚、孔道取向、孔隙率及表面润湿性等参数优化光吸收、反应物富集与传质效率的机制, 进而构建高效的宏观反应界面. 在此基础上, 前瞻性地提出并重点阐述了COF异质结膜这一集成平台: 在纳米尺度上, 利用界面内建电场显著加速载流子动力学, 有效抑制体相复合; 在宏观尺度上, 借助膜结构实现催化剂固定化与连续流操作, 大幅提升催化剂的运行稳定性和可回收性. 二者的协同作用不仅实现了光生电荷的空间分离, 同时优化了反应物在孔道内的扩散行为, 展现出显著的增效机制. 得益于异质结界面的高效电荷分离与膜结构提供的快速传质通道, 所构建的COF异质结膜在光催化产氢、污染物降解等应用中表现出优异的性能提升.

综上, 本文系统梳理了COF光催化剂从分子设计到宏观组装的跨尺度研究, 揭示了异质结与膜结构的协同集成是突破粉末体系应用瓶颈的关键路径. 未来研究应聚焦于规模化制备技术、应用导向的材料设计, 以及系统集成与可持续性评估. 本文旨在为开发兼具高本征活性与工程适用性的新型COF光催化体系提供理论借鉴, 推动光催化技术的实用化进程.

Abstract:

Transitioning covalent organic frameworks (COFs) from laboratory-scale photocatalysts to practical technologies requires overcoming two fundamental bottlenecks: rapid charge recombination at the microscopic level and mass transfer limitations coupled with the engineering challenges of particulate suspensions at the macroscopic level. This review presents a multiscale engineering strategy to bridge this gap, progressing from heterojunction design to membrane fabrication. We first provide a systematic assessment of COF-based heterostructures, incorporating metals, metal oxides, and inorganic semiconductors, to elucidate the structure-activity relationships governing excitonic dynamics. Special emphasis is placed on S-scheme COF-based heterojunctions, highlighting their superior capability in facilitating interfacial charge transfer while preserving high redox potentials. Subsequently, the focus shifts to the engineering of COF membranes via techniques such as interfacial polymerization and in-situ growth, emphasizing their structural merits in macroscopic processability. Critically, we propose the integration of heterojunction concepts into membrane architectures as a pivotal strategy to resolve the inherent trade-offs between the aggregation of powder catalysts and the limited semiconductor properties of traditional polymer membranes. By analyzing recent advances in heterostructured COF membranes, we highlight how this synergistic approach simultaneously enhances charge separation efficiency, substrate flux, and operational stability. We further discuss the application of these heterojunction and membrane systems in key photocatalytic processes, including H2 production, CO2 reduction, H2O2 production, and pollutant degradation. The review concludes by outlining a roadmap for overcoming scalability hurdles, offering a blueprint for the development of efficient, robust, and industrially relevant COF photocatalytic systems.
