Semiconductor photocatalysts play an indispensable role in the photocatalytic process. Two-dimensional covalent organic frameworks (2D-COFs), as a kind of innovative photocatalyst, have garnered tremendous attention. Herein, we report an amide-linked 2D-COF (COF-JLU19) with outstanding photocatalytic performance in water, designed through a multi-synergistic approach. The synergistic effects of the high porosity, photoactive framework, high wettability, and stability of COF-JLU19 led to an unprecedented enhancement in the photocatalytic activity and recyclability in water upon illumination by visible light. More importantly, amide-linked 2D-COF based electrospinning membranes were prepared, which also exhibited superior photocatalytic activity for the degradation of Rhodamine B in water with sunlight. This study highlights the potential of the multi-synergistic approach as a universal rule for developing COF-based photocatalysts to address environmental and energy challenges.

半导体光催化剂在光催化过程中起着不可或缺的作用。二维共价有机骨架（2D-COFs）作为一种创新的光催化剂，受到了极大的关注。在此，我们报告了一种通过多重协同方法设计的在水中具有出色光催化性能的酰胺连接的 2D-COF（COF-JLU19）。COF-JLU19 的高孔隙率、光活性骨架、高润湿性和稳定性的协同作用导致可见光照射下光催化活性和水中可回收性的前所未有的增强。更重要的是，制备了基于酰胺连接的 2D-COF 的静电纺丝膜，该膜还表现出优异的光催化活性，可在阳光下降解水中的罗丹明 B。
